【Abstract】 Bromopyridine substituted polystyrene resin and N-diphenyl phosphine pyrldi-ne substituted resin can be prepared by using chloromethylated polystyrene -dlv-inylbenzene. The N -diphenyl phosphine pyridine substituted polystyrene reactsith phenyl-cyanide palladium chloride complex forming supported catalysts. These catalysts were used in hydrogenation of mesityl oxide to prepare 4-methyt-pentanone- (2) . The activity and selectivity of the catalysts were investigated.更多还原
