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.
Oxidation of Secondary Amines with NiSO4-K2S2O8

The catalytic system consisting of NiSO4 and K2S2O8 has been found to be effective for the oxidation of secondary amines to imines. 1,2,3,4-Tetrahydroisoquinoline was oxidized to 3,4-dihydroisoquinoline as the main product with a small amount of isoquinoline.N-Benzylaniline gave N-benzylideneaniline and a N-N coupling dimer.
SUBSTITUENT EFFECT ON TORSIONAL BARRIERS IN N,N'-DIBENZYLHYDRAZOBENZENES.

Substituted hydrazobenzenes were prepared and their barriers to rotation measured by DNMR spectroscopy and correlated with ?-substituent constants with a reaction constant ρ300=-1.09.
