We report the syntheses, crystal structures, and characterization of the novel cis-dioxomolybdenum(VI) complexes [Tpm*(MoO2Cl)-O-VI](MoO2Cl3) (1) and [Tpm*(MoO2Cl)-O-VI](ClO4) (2), which are supported by the charge-neutral tris(3,5-dimethyl-1-pyrazolyl)methane (Tpm*) ligand. A comparison between isostructural [Tpm*(MoO2Cl)-O-VI](+) and Tp*(MoO2Cl)-O-VI [Tp* = hydrotris(3,5-dimethyl-1-pyrazolyl)borate] reveals the effects of one unit of overall charge difference on their spectroscopic and electrochemical properties, geometric and electronic structures, and O-atom-transfer (OAT) reactivities, providing new insight into pyranopterin molybdoenzyme OAT reactivity. Computational studies of these molecules indicate that the delocalized positive charge lowers the lowest unoccupied molecular orbital (LUMO) energy of cationic [Tpm*MoO2Cl](+) relative to Tp*MoO2Cl. Despite their virtually identical geometric structures revealed by crystal structures, the Mo-VI/Mo-V redox potential of 2 is increased by 350 mV relative to that of Tp*(MoO2Cl)-O-VI. This LUMO stabilization also contributes to an increased effective electrophilicity of [Tp*MoO2Cl](+) relative to that of Tp*MoO2Cl, resulting in a more favorable resonant interaction between the molydenum complex LUMO and the highest occupied molecular orbital (HOMO) of the PPh3 substrate. This leads to a greater thermodynamic driving force, an earlier transition state, and a lowered activation barrier for the orbitally controlled first step of the OAT reaction in the Tpm* system relative to the Tp* system. An Eyring plot analysis shows that this initial step yields an O Mo-IV-OPPh3 intermediate via an associative transition state, and the reaction is similar to 500-fold faster for 2 than for Tp*MoO2Cl. The second step of the OAT reaction entails solvolysis of the O Mo-IV-OPPh3 intermediate to afford the solvent-substituted Mo-IV product and is 750-fold faster for the Tpm* system at -15 degrees C compared to the Tp* system. The observed rate enhancement for the second step is ascribed to a switch of the reaction mechanism from a dissociative pathway for the Tp* system to an alternative associative pathway for the Tpm* system. This is due to a more Lewis acidic Mo-IV center in the Tpm* system.

The Name is 3,5-Dimethyl-1H-pyrazole. Through research, I have a further understanding and discovery of 67-51-6. Formula: C5H8N2

An efficient Zn(OTf)(2)-catalyzed regioselective C-N bond making reaction between a bunch of aryl/heteroaryl-substituted para-quinone methides as ideal 1,6-acceptors and various aromatic/non-aromatic aza-heterocycles bearing N-H moiety namely carbazoles, pyrazoles, indazole, benzotriazole and saccharin is reported. This 1,6-aza-Michael technique delivers predominantly NI-diarylmethyl-substituted heterocyclic scaffolds bearing a valuable phenolic moiety in good to high yields with an excellent regioselectivity. Furthermore, this LUMO lowering catalytic system allows different kinds of useful functionalities and excels with broad substrates under mild conditions. Importantly, our control experiments suggested that N2-adducts of indazole, benzotriazole and 3-methyl pyrazole as minor isomers were progressively converted into N1-adducts during the reaction via a retro-aza-Michael reaction triggered by Zn(OTf)(2), offering excellent regioselectivities of the products.

A strategy for C-H functionalization of arenes and heteroarenes has been developed to allow site-selective incorporation of various anions, including Cl, Br, OMs, OTs, and OTf. This approach is enabled by in situ generation of reactive, non-symmetric iodanes by combining anions and bench-stable Phl(OAc)(2). The utility of this mechanism is demonstrated via para-selective chlorination of medicinally relevant arenes, as well as site-selective C-H chlorination of heteroarenes. Spectroscopic, computational, and competition experiments describe the unique nature, reactivity, and selectivity of these transient, unsymmetrical iodanes.

This study provides a phenomenological method to describe the exponential growth, saturation, and decay of coronavirus disease 2019 (COVID-19) deaths and infections via a Monte Carlo approach. The calculations connect Gompertz-type trial distributions of infected people per day with the distribution of deaths adopting two gamma distributions to account for the elapsed time that encompass the incubation and symptom onset to death periods. The analyses include death data from the USA, Brazil, Mexico, the United Kingdom (UK), India, and Russia, which comprise the four countries with the highest number of deaths and the four countries with the highest number of confirmed cases, as of August 07, 2020, according to theWorld Health Organization webpage. The Gompertz functions were fitted to the data of weekly averaged confirmed deaths per day by mapping the chi(2) values. The uncertainties, variances, and covariances of the model parameters were calculated by propagation, taking into account the standard errors of the data for each epidemiological week. The fitted functions for the average deaths per day for the USA and India have an upward trend, with the former having a higher growth rate and quite huge uncertainties. For Mexico, the UK, and Russia, the fits are consistent with a downward-sloping pattern. For Brazil we found a subtle trend down but with significant uncertainties. The USA, UK, and India data showed first peaks with higher growth rates compared with the second ones (4.2, 2.2, and 3.5 times higher, respectively), demonstrating the benefits of nonpharmacological interventions of sanitary measures and social distance flattening the secondary peaks of the pandemic. For the case of the USA, however, a third peak seems quite plausible, most likely related with the recent relaxation policies. Brazil’s data are satisfactorily described by two highly overlapped Gompertz functions with similar growth rates, suggesting a two-step process for the pandemic spreading. For the cases of Mexico and Russia single peaks with smoother slopes fitted the data satisfactorily. The 95% confidence intervals for the total number of deaths (x10(3)) predicted by the model for August 31, 2020, are 160 to 220, 110 to 130, 59 to 62, 41.3 to 41.4, 54 to 63, and 16.0 to 16.7 for the USA, Brazil, Mexico, the UK, India, and Russia, respectively. Our estimates for the point prevalences of infections are compared with some preliminary data from serological studies and/or model calculations focused on the USA, Brazil, and UK scenarios. The point prevalences and 95% confidence intervals for August 1, 2020, were estimated to be 5.7 (3.9-7.5)%, 8.9 (7.4-10.3)%, 9.3 (8.3-10.3)%, 5.7 (4.5-6.9)%, 0.9 (0.8-1.0%), and 1.2 (1.0-1.3)% for the USA, Brazil, Mexico, the UK, India, and Russia, respectively. The method represents an effective few-parameter framework to estimate the line shape of the infection curves and the uncertainties of the relevant parameters based on the actual death data of a pandemic.

Importance: treatment of dementia in individuals with comorbidities is complex, leading to potentially inappropriate prescribing (PIP). The impact of PIP in this population is unknown. Objective: to estimate the rate of PIP and its effect on adverse health outcomes (AHO). Design: retrospective cohort. Setting: primary care electronic health records linked to hospital discharge data from England. Subjects: 11,175 individuals with dementia aged over 65 years in 2016 and 43,463 age- and sex-matched controls. Methods: Screening Tool of Older Persons’ Prescriptions V2 defined PIP. Logistic regression tested associations with comorbidities at baseline, and survival analyses risk of incident AHO, adjusted for age, gender, deprivation and 14 comorbidities. Results: the dementia group had increased risk of PIP (73% prevalence; odds ratio [OR]: 1.92; confidence interval [CI]: 83-103%; P < 0.01) after adjusting for comorbidities. Most frequent PIP criteria were related to anti-cholinergic drugs and therapeutic duplication. Risk of PIP was higher in patients also diagnosed with coronary-heart disease (odds OR: 2.17; CI: 1.91-2.46; P < 0.01), severe mental illness (OR: 2.09; CI: 1.62-2.70; P < 0.01); and depression (OR: 1.81; CI: 1.62-2.01; P < 0.01). During follow-up (1 year), PIP was associated with increased all-cause mortality (hazard ratio: 1.14; CI: 1.021.26; P < 0.02), skin ulcer and pressure sores (hazard ratio: 1.66; CI: 1.12-2.46; P< 0.01), falls (hazard ratio: 1.37; CI: 1.15-1.63; P < 0.01), anaemia (hazard ratio: 1.61; CI: 1.10-2.38; P < 0.02) and osteoporosis (hazard ratio: 1.62; CI: 1.022.57; P < 0.04). Conclusion: patients with dementia frequently receive PIPs, and those who do are more likely to experience AHO. These results highlight the need to optimise medication in dementia patients, especially those with comorbidities.

Here in, the effects of FeSiAl particle size on the dielectric and microwave absorption properties of FeSiAl/Al2O3 composites were studied. FeSiAl/Al2O3 composites containing 18-25 mu m, 25-48 mu m, and 48-75 mu m FeSiAl particles were prepared by hot-pressed sintering based on uniformly mixed FeSiAl and Al2O3 powders. Results show that the real permittivity and the imaginary permittivity are significantly promoted with increasing FeSiAl particle size, which is ascribed to the enhanced interfacial polarization and conductance loss. In addition, the favorable matching impedance and suitable attenuation coefficient enabled the composite containing 25-48 mu m FeSiAl powder to show a minimum reflection loss of -34.4 dB at 11.7 GHz and an effective absorption bandwidth (<-10 dB) of 1.4 GHz in 11.0-12.4 GHz, when the thickness is 1.1 mm. By adjusting the thickness to 1.4 mm, the effective absorption bandwidth of the composite reaches a maximum value of 2.0 GHz in the 8.3-10.3 GHz range, indicating tunable, strong, and highly efficient microwave absorption performance.

A new semi-theoretical equation is suggested for correlation of solid-liquid solubility data with temperature. The (solid + liquid) equilibrium for Terephthaldialdehyde, 4-Nitro-o-phennylenediamine, 2,4-dihydro- 5-methyl-2(4-methylphenyl)-3H-pyrazol-3-one (also named 1-(p-toly1)-3-methyl-5pyrazolone (PTMP)), 2-Amino-5-methylthiazole and 5-chloro-1-methyl-4-nitroimidazole in 18 solvents is correlated with semi-empirical models at temperatures T = 273.15 – 318.15 K under a pressure of 101.2 kPa. Moreover, a modified Apelblat model, lambda h model, Wilson model, NRTL model, new flexible equation as Akbari, Dideban and Farhang model (ADF) and for first time the modified Scatchard-Hildebrand equation were utilized to calculate the experiment values. The performance of both ADF and modified Scatchard-Hildebrand equation have been checked by calculating the solubility data with the AARD% of 1.3808% (for 775 data points) and 0.65% (for 100 data points), respectively. The Wilson model is applied to estimate the mixing Gibbs energy, mixing enthalpy, mixing entropy, activity coefficient (ln gamma(infinity)(1)) and reduced excess enthalpy (H-I(E,infinity)) at infinitesimal concentration were calculated.
