摘要：
A new phosphine-containing polymer ligand, zeolite-supported polysiloxane-triphenylphosphine (Zeo-SiO-P), has been prepared from zeolite, triphenylphosphine, ethyl orthosilicate and water by a very simple method. A palladium complex of zeolite-supported polysiloxane-triphenylphosphine (Zeo-SiO-P-Pd) has been found to be able to catalyze the hydrogenation of various unsaturated compounds as nitrobenzene and methacrolein to corresponding reduction compounds at 40 degrees C under atmospheric hydrogen pressure in 100% yield. This catalyst is very stable in the hydrogenation anti can be reused several times without appreciable change in catalytic activity. (C) 1999 John Wiley & Sons, Ltd.
