Abstract

Several triethoxysilylated ligands have been synthesized and after complexation with a metal followed by the hydrolysis, efficient and recyclable heterogeneous catalysts were obtained. Three examples of catalytic reactions have been studied with these organic-inorganic hybrid materials obtained by the sol-gel process: (1) asymmetric reduction of prochiral ketones by hydride transfer, (2) Suzuki’s coupling reaction and (3) metathesis of dienes and enynes.
