A diphosphino-functionalised MCM-41 anchored platinum complex (MCM-41-2P-Pt) was conveniently synthesised from commercially available and cheap γ-aminopropyltriethoxysilane via immobilisation on MCM-41, followed by reactiopn with diphenylphosphinomethanol and potassium chloroplatinite. It was found that the title complex is a highly efficient catalyst for the hydrosilylation of olefins with triethoxysilane and can be recovered and recycled by a simple filtration of the reaction solution and used for at least 10 consecutive reactionss without any decrease in activity.

The hydrosilylation of alkenes with triethoxysilane has been achieved at 120 °C in the presence of 0.01. mol% of thioether-functionalized MCM-41 anchored rhodium complex, affording the corresponding addition products in 68-91% yields. This supported rhodium complex can be reused several times without noticeable loss of activity. Our system not only solves the basic problems of catalyst separation and recovery, but also avoids the use of phosphine ligands.

An MCM-41-immobilised bidentate nitrogen platinum complex (MCM-41-2N-Pt) was very conveniently synthesised from commercially available and cheap 3-(2-aminoethylamino)propyltrimethoxysilane by immobilisation on the mesoporous silica nanoparticles, MCM-41, followed by reaction with potassium chloroplatinite. It was found that the MCM-41-2N-Pt complex is a highly efficient catalyst for the hydrosilylation of olefins with triethoxysilane and can be easily recovered and reused several times without significant loss of activity.

MCM-41-supported bidentate phosphine rhodium complex (MCM-41-2P-RhCl 3) was conveniently synthesized from commercially available and cheapγ-aminopropyltriethoxysilane via immobilization on MCM-41, followed by reacting with diphenylphosphinomethanol and rhodium chloride. It was found that the title complex is a highly efficient catalyst for the hydrosilylation of olefins with triethoxysilane and can be recovered and recycled by a simple filtration of the reaction solution and used for at least 10 consecutive trials without any decreases in activity.
