Abstract

Secondary amines are obtained in moderate-good yields by reduction of crude imines prepared from N-alkyltriethoxyiminophosphoranes and aldehydes via the aza-Wittig reaction. N-Alkyltriethoxyiminophosphoranes are synthesized by one-pot azidation of alkyl bromides followed by Staudinger reaction.
