The 1,2- and 1,3-monoazabisylides (5 and 11, respectively) were prepared in situ by the reactions of 1-<<(triphenylphosphorylidene)amino>methyl>benzotriazole (betmip, 2) with diethyl phosphite anion and methylenetriphenylphosphorane, respectively, followed by treatment with butyllithium.The synthetic versatility of the new reagents 5 and 11 is illustrated by convenient methods for the preparation of isoquinoline, 2-azabutadienes, 2,3-diarylpyrroles, and 2-(3H)-benzazepine.
