Synthesis of Amidines Using <i>N</i>-Allyl Ynamides. A Palladium-Catalyzed Allyl Transfer through an Ynamido−π-Allyl Complex

Abstract

A de novo transformation of N-allyl-N-sulfonyl ynamides to amidines is described featuring a palladium-catalyzed N-to-C allyl transfer via ynamido-palladium-pi-allyl complexes.
