•New palladium phosphine complex•CS bond cleavage during complexation•Pd(II) catalyzed Suzuki and Heck coupling reactions
Reaction of ligand, L-CH2Ph with Pd(CH3CN)2Cl2 in acetonitrile in presence of PPh3 and subsequent addition of NaClO4 yielded Pd(II) complex, [Pd(L)(PPh3)](ClO4) 1 due to the SC (CH2Ph) bond cleavage during complexation. Complex 1 was characterized by spectral analysis and the structure was authenticated by single crystal X-ray diffraction. The diffraction analysis revealed that the monoanionic ligand binds with palladium (II) in (N, N, S) fashion in a distorted square planar geometry where the fourth position is occupied by one tri phenyl phosphine group. One ClO4− ion satisfies the charge of the former aggregate, [Pd(L)(PPh3)]+. The complex [Pd(L)(PPh3)](ClO4), 1 exhibits a very good catalytic activity towards CC bond formation.
Graphical abstractNewly designed Schiff base ligand, L-CH2Ph and its palladium complex, [Pd(L)(PPh3)](ClO4) have been synthesized and characterized unequivocally. The complex shows catalytic activity towards CC bond formation in presence of air and moisture.Figure optionsDownload full-size imageDownload as PowerPoint slide
