The N,N bond cleavage in hydrazines to amines via low-valenttitaniumreagent prepared in situ by treatment of TiCl4 with Mg powder in THF or CH2Cl2-Et2O is described. The reaction proceeds smoothly under mild conditions to afford amines in good to excellent yields with diverse functional group tolerance such as chloride, methoxyl, benzyloxyl, ester, acyl, as well as C,C double bonds and benzyl-nitrogen

An unexpected reaction of N,N-disubstitutedhydrazine with naphthol and its analogues under simply thermal conditions has been disclosed. 2-Naphthol reacted with various N,N-disubstitutedhydrazines under argon to afford 1-amino-2-naphthol and the corresponding secondary amines in excellent yields. Ortho amination of 2-naphthols, hydroxyquinoline, and naphthalenamine occurred when they reacted with
