摘要：

Selective hydrogenations of different alpha,beta-unsaturated aldehydes into allylic alcohols with immobilized homogeneous catalysts are reported. Different kinds of catalysts were used: supported aqueous-phase catalysts (RuCl2(TPPTS)3/SiO2 and RuH2(TPPTS)4/SiO2) and supported homogeneous catalysts (especially phosphino-iridium catalysts like IrCl3{(C6H5)P[(CH2)3SiO3/2]2.2N[(CH2)3SiO3/2]3.2SiO2}3). Some of them are good alternatives to homogeneous catalysts since they are chemoselective, sometimes stereoselective and easy to recover.
