Title: On the Reactivity of α-(Triphenylphosphoranylidene)-benzylphenylketene with Nitrogen Compounds: Synthetic and Mechanistic Implications
Author: Cunha, Silvio
Kascheres, Albert
Abstract: The reactivity of α-(triphenylphosphoranylidene)-benzylphenylketene, a stabilized phosphorus ylide derived from diphenylcyclopropenone, toward nitrogen compounds was investigated. Particularly, the reaction of diethyl azodicarboxylate with α-(triphenylphosphoranylidene)-benzylphenylketene provides a new route to polysubstituted N-acyl carbamates.
A reatividade do ilídeo de fósforo estabilizado derivado da difenilciclopropenona, o α-(trifenilfosforanilideno)-benzilfenilceteno, frente a compostos nitrogenados polifuncionalizados foi investigada. Em particular, a reação do α-(trifenilfosforanilideno)-benzilfenilceteno com o azodicarboxilato de etila pode se constituir como um novo método de síntese de N-acil-carbamatos densamente substituidos.
