Aromatic and heteroaromatic organometallics (Grignard and lihium compounds) reacts with diphenyl phosphorazidate (DPPA) to give labile phosphinyltriazenes.A study of the conversion of phosphinyltriazenes into amines has revealed that reductive work-up with aluminum hydride gives much better results than acidic or alkaline work-up.Sequential treatment of aromatic and heteroaromatic organometallics with DPPA, followed by aluminum hydride provides a convenient new method for the preparation of aromatic and heteroaromatic amines.Keywords - organometallic; aromatic halide; Grignard compound; organolithium compound; aromatic amine; heteroaromatic amine; phosphinyltriazene; hydride reduction; diphenyl phosphorazidate
