A highly effective solvent-free protocol for the Buchwald–Hartwig amination of unactivated aryl chlorides is described. The effect of various [Pd(NHC)] pre-catalyst systems on the reactivity has been studied. [Pd(IPr*)(cin)Cl] is reported as the complex of choice for the transformation.

tridentate NNN-cobalt complex for the hydrosilylative reduction of secondary amides with the low-cost PMHS as the hydride donor reductant. In this catalytic protocol, a wide range of secondary amides, including benzamide-type and aliphatic carboxylic acid-derived secondary amides, served as suitable substrates to afford their corresponding secondary amines in moderate to excellent yields. The scaled-up reaction
