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. ...
The chiral phosphoric acid catalyzed enantioselective transfer hydrogenation of various ketimines was achieved by the use of 2-aryl indoline as the hydrogen donor. Corresponding chiral amines were obtained in good chemical yields with excellent en...

Described herein are two novel types of double C(sp(3))-H bond functionalizations triggered by a sequential hydride shift/cyclization process: (1) construction of a bicyclo[3.2.2]nonane skeleton by a [1,6]- and [1,5]-hydride shift sequence and (2)...
