%X the reactivity of ¦Á-(triphenylphosphoranylidene)-benzylphenylketene, a stabilized phosphorus ylide derived from diphenylcyclopropenone, toward nitrogen compounds was investigated. particularly, the reaction of diethyl azodicarboxylate with ¦Á-(triphenylphosphoranylidene)-benzylphenylketene provides a new route to polysubstituted n-acyl carbamates.
