Abstract

A series of monomeric arylpalladium (II) complexes LPd (Ph) X (L= 1-AdP t Bu2, P t Bu3, or Ph5FcP t Bu2 (Q-phos); X= Br, I, OTf) containing a single phosphine ligand have been prepared. Oxidative addition of aryl bromide or aryl iodide to bis-ligated palladium (0) complexes of bulky, trialkylphosphines or to Pd (dba) 2 (dba= dibenzylidene acetone) in the presence of 1 equiv of phosphine produced the corresponding arylpalladium (II) ...
