Preparation, characterization and structural study of a dichlorobis (۴’-bromobiphenyl-۴-yl)diphenylphosphine platinum(II) complex and checking the catalytic activity under optimal conditions

In this article, potassium tetrachloroplatinate(II), K۲PtCl۴, has reacted with an organic ligand [L: Br(C۶H۴)۲P(C۶H۵)۲] and created the complex PtCl۲L۲ (yield= ۸۷% and Melting point= ۲۱۵-۲۱۷°C), then this compound with different techniques including FT-IR, ۱H, ۳۱P, ۱۳C and ۱۹۵Pt-NMR spectroscopy have been identified. Spectral analysis showed that the desired complex was synthesized with trans structure. In the following, the catalytic activity of this compound has been investigated by performing Suzuki and Heck coupling reactions for various aryl halides under optimal conditions including temperature, type of solvent, type of base, different amounts of base and different amounts of catalyst. The obtained results have shown the remarkable catalytic activity of this complex for the synthesis of the expected products.
