Abstract: During the past years, the interest in complexes of transition metals with organophosphorus ligands has been growing considerably in the light of their versatile applications in coordination chemistry and homogenerous catalysis. The palladium system has good prospects in the catalytic application. Particularly for a lack of selectivity under classic conditions or for base sensitivity of the functional groups, transition metal catalysis under mild and neutral conditions offers a promising and superior alternative. A (1,2-diaryl)vinylphosphine ligand has one aryl group at the α-position and one aryl group at the β-position, respectively. The ligand more steric hindrance and electron-richness around the phosphorus atom was synthesized. Complex of palladium-(1,2-diaryl)vinylphosphine as a catalyst shows highly catalytic activity in Sonograshira cross coupling reaction.

Key words: (1,2-Diaryl)vinylphosphine ligand, Palladium, Sonograshira reaction
