【Abstract】 Alkylation of Phenylacetonitrile was realized from phenylacetonitrile and benzyl chloride by using PS-PEG-400 as triphase phase transfer catalyst. The results showed that this novel synthetic method has the advantages of good yields and milder reaction conditions. Moreover, the catalysts used could be recovered conveniently and reused efficiently.更多还原
