presence of S-benzyl isothiouronium chloride as a recoverableorganocatalyst is reported. A wide range of ketones as well as amines were found to give the expected products in moderate to excellent yields. The direct reductive amination of ketones using the Hantzsch ester in the presence of S-benzyl isothiouronium chloride as a recoverableorganocatalyst is reported. A wide range of ketones as well as

Here, we describe the formation and use of silyl cobalt (III) dihydride complexes as powerful catalysts for the hydrosilylation of a variety of imines starting from a low-valent well-defined cobalt (I) complex. The reaction is efficient at low catalyst loadings with a diverse range of imines bearing various protecting groups, as well as aliphatic ketimines and quinoline. Kinetics, DFT calculations
