Ruthenium complex immobilization on layered silicate materials

Abstract

In this work, hydrogenation of sorbic acid to cis-hex-3-enoic acid using homogeneous Ru catalyst [Cp*Ru(sorbic acid)]Tf (Tf = CF 3 SO 3 -) immobilized to smectite materials by means of ion exchange has been studied. The immobilized catalyst was utilized for heterogeneous hydrogenation of sorbic acid to the desired cis-hex-3-enoic acid, achieving the selectivity of up to 95% and the possibility of the catalyst to be reused.
