Azo Anions in Synthesis: α-Amino Carbanion Equivalents from t-Butyldiphenylmethylhydrazones

Baldwin, Jack E.,Adlington, Robert M.,Newington, Ian M.

, p. 176 - 178 (1986)

α-Amino carbanion equivalents (=C(1-)NH2) and α-hydrazino anion equivalents (=C(1-)NHNH2) are readily accessible from the C-alkylation products of t-butyldiphenylmethylhydrazones; these azoalkanes can be efficiently transformed into amines, hydrazines, and also alkanes under mild reaction conditions.
