Özet

Three new secondary carbene palladium(II) complexes (1b-3b) were synthesized via oxidative insertion of Pd-2(dba)(3) (dba = dibenzylideneacetone) into the C-Cl bond of dialkyl(chloromethylene) ammonium chloride salts ([R2NCHCl]Cl-+(-)). All complexes have been characterized by H-1, C-13, and P-31 NMR analysis. X-ray diffraction studies on single crystal of 3b confirm the cis square planar geometry. Complexes (1b-3b) have been proved to be efficient catalysts in the Heck coupling of styrene with 4-bromoacetophenone. (C) 2012 Elsevier B.V. All rights reserved.
