Reduction of hydrazines to amines with aqueous solution of titanium(iii) trichloride

N-N bond cleavage in hydrazines is widely used in the preparation of amines and thus occupies a significant place in organic synthesis. In this paper, we report a new method for the reductive cleavage of N-N bonds in hydrazines by commercially available and cheap aqueous titanium(iii) trichloride. The reaction proceeds smoothly under a broad pH range from acidic to neutral and basic conditions to afford amines in good yields. This method is compatible with substrates containing functionalities such as C-C double bonds, benzyl-nitrogen bonds, benzyloxy and acyl groups. The Royal Society of Chemistry 2011.

Regioselective Synthesis of 1-Alkyl-1-phenylhydrazines, 2-Alkyl-1-phenylhydrazines, and 1,2-Dialkyl-1-phenylhydrazines

1,2- and 1,1-disubstituted and 1,1,2-trisubstituted hydrazines are obtained by reaction of (2-phenylhydrazino)triphenylphosphonium bromide with butyllithium, followed by addition of alkyl halides and alkaline hydrolysis.
