Electronic effects in the catalytic hydrosilylation with in-situ generated iron(II)-catalysts was written by Muller, Keven;Schubert, Anett;Jozak, Thomas;Ahrens-Botzong, Annegret;Schuenemann, Volker;Thiel, Werner R.. And the article was included in ChemCatChem in 2011.Electric Literature of C9H9N3 This article mentions the following:
In combination with different aromatic N,N-donors, iron acetate and octanoate are suitable catalyst precursors for the hydrosilylation of carbonyl compounds Iron octanoate can be used to perform this catalytic transformation in cheap and non-toxic petrol ether or heptane as the solvent and with versatile polymethylhydrosiloxane (PMHS) as the silane source. Investigation of the performed catalyst (iron octanoate + N,N-ligand + PMHS) by using Moessbauer spectroscopy suggests that the active species is a high-spin iron(II) system. In the experiment, the researchers used many compounds, for example, 2-(5-Methyl-1H-pyrazol-3-yl)pyridine (cas: 19959-77-4Electric Literature of C9H9N3).
2-(5-Methyl-1H-pyrazol-3-yl)pyridine (cas: 19959-77-4) belongs to pyrazole derivatives. As is the case with imidazoles, the pyrazole ring offers many opportunities to create new multiring systems that incorporate this heterocycle. Pyrazoles and pyrimidines have diverse biological and pharmacological activities. There are a number of antimicrobial compounds containing pyrazole moiety as the core unit. Pyrazofurin is important antimicrobial drug and 2-methylpyrimidine-4-ylamine derivatives I and II were found to be effective inhibitors of Escherichia coli PDHc-E1 with antibacterial and antifungal activity.Electric Literature of C9H9N3
