✦ Synopsis

Lithium derivatives of varied aromatic, heterocyclic, aliphatic, and alicyclic primary amines react efficiently with azidotris(diethylamino)phosphonium bromide in THF at low temperatures to give azides, lithium bromide, nitrogen, and tris(diethylamino)phosphorimine.

Lithium hydrazonides, prepared by reactions of hydrazones with n-BuLi/hexane in THF at -78°C, are converted by azidotris(diethylamino)phosphonium bromide in THF at 0°C efficiently, rapidly, and safely to their corresponding diazo compounds along with tris(diethylamino)phosphorimine, nitrogen, and li
