Abstract

A series of 2,6-dibenzhydryl-N-(2-aryliminoacenaphthylenylidene)-4- chlorobenzenaminopalladium(II) chloride complexes (C1-C6) were prepared and fully characterized by FT-IR and NMR spectroscopy, and by elemental analysis. The molecular structures of representative complexes C2 and C6 were confirmed as square planar at the palladium center by single crystal X-Ray diffraction. All palladium complexes exhibited good activity in the Heck cross-coupling reaction with conversions greater than 90%. Catalytic activity trends were attributed to differences in the solubility of the pre-catalysts; palladium complexes bearing more soluble alkyl-substituents performed with higher catalytic activities. © 2012 Elsevier B.V.
