Pyrazoles are synthesized by the reaction of α,β-unsaturated aldehydes with hydrazine and subsequent dehydrogenation. 761446-44-0, formula is C10H17BN2O2, Name is 1-Methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole. Substituted pyrazoles are prepared by condensation of 1,3-diketones with hydrazine (Knorr-type reactions). For example, acetylacetone and hydrazine gives 3,5-dimethylpyrazole. HPLC of Formula: 761446-44-0.
Li, Meng-Yao;Han, Pengbo;Hu, Tian-Jiao;Wei, Dong;Zhang, Ge;Qin, Anjun;Feng, Chen-Guo;Tang, Ben Zhong;Lin, Guo-Qiang research published 《 Suzuki-Miyaura Coupling Enabled by Aryl to Vinyl 1,4-Palladium Migration》, the research content is summarized as follows. An efficient Suzuki-Miyaura coupling enabled by a controllable 1,4-palladium migration was realized to afford stereodefined multisubstituted olefins and 1,3-dienes. The reaction exhibited remarkable broad substrate scope, excellent functional-group tolerance, versatile conversion with obtained products, and easy scalability. The practicality of this method was highlighted by the aggregation-induced emission feature of the produced olefins and 1,3-dienes, as well as the capability of affording geometric isomer pairs with a marked difference on photoluminescent quantum yield values.
