Recyclable rhodium-Cp′-heterogenized catalysts for hydrogenation of olefins

Autor: Silvana I. Wolke, Ricardo Gomes da Rosa, Fernanda Rosi Soares Pederzolli

Publikováno v: Journal of Catalysis. 360:201-212

Immobilized catalysts were prepared by mixing the ligand Cp′, [C5Me4(n-propyl-Si(OEt)3)], with RhCl3·xH2 O for subsequent reaction with silica Aerosil 200 (system A) or by copolymerization with TEOS (system B). Both systems were applied on olefin
