Palladium polyether diphosphinite complex anchored on polyethylene glycol is reported as an efficientcatalyst for Heck coupling reactions. The catalyst is soluble in the solvent with reactants and products during reaction and can be separated from reaction media in biphasic form by the addition of anti-solvent like n-hexane and further recycled. The developed methodology offers mild reaction condition

techniques. The sizes of in situ formed Pd nanoparticles were greatly affected by the substituent in ancillary ligand, which in turn influenced their catalytic activity towards Heck coupling reaction. The in situ formed Pd nanoparticles during Heckreaction were removed from the reaction medium and analyzed using HR-TEM to estimate the sizes of the Pd nanoparticles. Complex [Pd(ONO)((N-benzylcarbamothioyl)benzamide)]

reacted with PdCl 2 (CH3 CN) 2 in dichloromethane to form the respective palladium(II) complexes ( C1 – C7 ). All organic and palladium compounds were characterized by FT-IR and NMR spectroscopy, as well as by elemental analysis. The molecular structures of the complexes C4 , C5 and C7 were determined by single crystalX-ray diffraction studies and revealed distorted square geometries at each palladium
