Abstract

The catalytic acvtivity of dimeric and monomeric ortho-palladated complexes [Pd{C6H2(CH2NH2-(OMe)2,3,4}(µ-Cl)]2)2) and [Pd{C6H2(CH2NH2-(OMe)2,3,4}Cl(PPh3)](3), was investigated in Heck cross-coupling reaction. These complexes are more active and efficient catalysts for Heck cross-coupling reaction. The palladium complexes 2 and 3 is employed in the Heck cross-coupling reaction between styrene and acrylate with several aryl halides. High yields of corresponding C–C products, low catalyst loadings, mild reaction conditions and short reaction times are important features of these homogeneous reactions. The cross-coupled products were produced in high yields using catalytic amounts of [Pd{C6H2(CH2NH2-(OMe)2,3,4}(µ-Cl)]2 or [Pd{C6H2(CH2NH2-(OMe)2,3,4}Cl(PPh3)] as a thermally stable and oxygen insensitive complexes in NMP at 130 ºC.
