摘　　要：[Poly(styryl)bipyridine]palladium(O),a polymer-bound hydrogrnation catalyst,was characterized by DRS,ESCA and electron microscopy.This material was used as cata-lyst for the vinylation of ary liodides.It was found that the catalytic activlty is comparableto that of the homogeneous catalyst and is not remarkably lowered on being used threetimes With this catalyst,a series of substituted stilbenes,cinnamic acids and methylcinnamates was prepared in high yields.[Poly (styryl) bipyridine) palladium (0), a polymer-bound hydrogenation catalyst, was characterized by DRS, ESCA and electron microscopy. This material was used as catalyst for the vinylation of ary liodides. It was found that the catalytic activity is comparable to that of the homogeneous catalyst and is not remarkably lowered on being used three times. With this catalyst, a series of substituted stilbenes, cinnamic acids and methyl cinnamates was prepared in high yields.
