The hydrosilylation of alkenes is one of the most important methods for the synthesis of organosilicon compounds. In addition to the platinum‐catalyzed hydrosilylation, silyl radical addition reactions are notable as economic reactions. ...

BrØnsted acids have been employed primarily as catalysts for the formation and cleavage of C-O bonds, such as hydrolysis and formation of esters and acetals. BrØnsted acids have emerged as efficient catalysts for a range of carbon-carbon bond form...
B(C6F5)(3)-catalyzed hydrodesulfurization of carbonsulfur bonds was achieved using triethylsilane as the reducing agent. The corresponding products were obtained in good yields under mild reaction conditions. This protocol could be applied to the ...
Chiral 2-substituted 2,3-dihydro-4-quinolones were synthesized based on the chiral phosphoric acid catalyzed intramolecular aza-Michael addition reaction using N-unprotected 2-aminophenyl vinyl ketones as substrates in good yields with high enanti...
