English abstract The reactivity of alpha-(triphenylphosphoranylidene)-benzylphenylketene, a stabilized phosphorus ylide derived from diphenylcyclopropenone, toward nitrogen compounds was investigated. Particularly, the reaction of diethyl azodicarboxylate with alpha-(triphenylphosphoranylidene)-benzylphenylketene provides a new route to polysubstituted N-acyl carbamates
Portuguese abstract A reatividade do ilídeo de fósforo estabilizado derivado da difenilciclopropenona, o alfa-(trifenilfosforanilideno)-benzilfenilceteno, frente a compostos nitrogenados polifuncionalizados foi investigada. Em particular, a reação do alfa-(trifenilfosforanilideno)-benzilfenilceteno com o azodicarboxilato de etila pode se constituir como um novo método de síntese de N-acil-carbamatos densamente substituidos
