An example of homogeneous Mo-catalyzed direct N-alkylation of anilines or nitroarenes with alcohols is presented. The DFT aimed design suggested the easily accessible bis-NHC-Mo(0) complex features a strong hydride-donating ability, achieving effective N-alkylation of anilines or challenging nitroarenes with alcohols. The enhanced hydride-donating strategy should be useful in designing highly active

of arylamines via transfer hydrogenation in the absence of pressurized hydrogen and basic or acidic additives was achieved in a tandem reaction. This process was further extended to the CN bond reduction and N-alkylation of a variety of imines with ethanol, the latter acting as a hydrogen and acetaldehyde source, which allowed for the reduction and subsequent condensation to yield the corresponding

diazonium salts as catalysts to catalyze reductive aminations of carbonyls and the synthesis of bis (3-indolyl)methane derivatives. The catalytic system showed good tolerance to substituents in the substrate in these two reactions. The separation yields of reductive aminations range from moderate to excellent. The separation yield of the reaction for synthesizing bis(3-indolyl)methane derivatives ranges
