Multi-amino groups and nitrogen donors compound was discovered as an organocatalyst for N-alkylation of alcohols with amines in the presence of Mo(CO)6. The Mo(CO)6/organocatalyst binary system has shown to be a highly active catalyst for the N-alkylation reaction between alcohols and amines with excellent tolerance of variable starting materials bearing different functional groups. Of particular note

The one‐pot synthesis of N‐substituted secondary amines from nitrobenzenes and benzonitriles has been developed (see scheme). This report presents a versatile and simple method for the synthesis of N‐substituted amines in excellent yield and high efficiency from nitro and nitrile compounds with alcohols.

A highly efficient Au/AgâMo nano-rods catalyst was prepared for the one-pot synthesis of imine and amine using equal molar ratio of nitrobenzene and alcohol as starting materials, and bio-based glycerol as the hydrogen source. The reaction mechanism of the nitrobenzene reduction, amine and aldehyde coupling, and imine reduction was explored.

As the sustainable and promising hydrogen source, here, glycerol was directly used as the hydrogen source for the reductive amination of alcohol using nitrobenzene as the starting material. The amination of alcohols, especially aliphatic alcohols with different structures, was realized, and mono- or disubstituted amines were synthesized with excellent yields. The reaction mechanism was also explored
also report an interesting direductive amination of 2-ethylbutanal. A direct reductive amination of aldehydes with anilines is performed with a ruthenium(II)-(arene) catalyst. The [RuCl2(p-cymene)]2/Ph2SiH2 catalytic system is very efficient for the synthesis of secondary amines and tertiary amines in good yields, and is highly chemoselective, tolerating a wide range of functional groups, such as NO2
