Abstract

original image

Worth diene for: The butadienylphosphine L (see scheme), obtained on a large scale from a new synthetic method, is an efficient ligand in Ullmann-type copper-catalyzed arylation reactions. The use of this phosphorus ligand made it possible to follow the reaction by 31P NMR spectroscopy and thus to propose a mechanism for the Ullmann reaction.
