N2 - 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.
