Abstract

The mixture of isomers of silylated cyclopentadiene derivative C₅H₅CH₂CH₂Si(OMe)₃ (1) has been used for the syntheses of the mononuclear Rh(I) complexes [η⁵-C₅H₄(CH₂) ₂Si(OMe)₃]Rh(CO)₂ (3), [η⁵-C₅H₄(CH₂) ₂Si(OMe)₃]Rh(COD) (4) and [η⁵-C₅H₄-(CH₂) ₂Si(OMe)₃]Rh(CO) (PPh₃) (5). Upon entrapment of 3-5 in silica sol-gel matrices, air stable, leach-proof and recyclable catalysts 6-8 resulted. Their catalytic activities in some hydrogenation processes were compared with those of the non-immobilized complexes, 3-5, as well as with those of homogeneous and heterogenized non-silylated analogs, 9-14.
