(Chemical Equation Presented). A mesoporous crystalline material (MCM-41)-supported mercapto and vinyl platinum complex [MCM-41-(SH-Pt)-(Vi-Pt)] was prepared and characterized by Fourier Transform-Infrared spectroscopy, thermogravimetry, transmission electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. The catalytic activity of MCM-41-(SH-Pt)-(Vi-Pt) was evaluated through the hydrosilylation of styrene with methyldiethoxysilane. MCM-41-(SH-Pt)-(Vi-Pt) shows superior activity for hydrosilylation compared with MCM-41-Vi-Pt and MCM-41-SH-Pt respectively, but the selectivity of three catalysts is almost the same. The catalyst MCM-41-(SH-Pt)-(Vi-Pt) could efficiently be recovered by a simple filtration and reused in four consecutive cycles without significant loss of catalytic activity and selectivity.

The reaction of ligand L with PtCl2 leads to a novel structural motif of octahedral ortho-metalated complex of formula [Pt(L-H) Cl3] 1. This result is a consequence of drastic conditions of reaction and preferred Pt(IV) octahedral coordination geometry. The new compound has been characterised on the basis of the spectroscopic data in solution, and its structure confirmed in the solid state by X-ray crystallography (1a - [Pt(L-H)Cl3]·MeOH, 1b - [Pt(L-H)Cl 3]·C6H5CH3). This article reports organoplatinum (IV) complex 1 as effective and highly selective catalyst precursor in the hydrosilylation of styrene and terminal alkynes.
