| Abstract: | A study has been made of arylation of activated alkenes with aryl chlorides homogeneously catalysed by palladium acetate in the presence of triphenylphosphine or tri-p-tolylphosphine. Electron-withdrawing substituents in the aryl chloride favour the reaction. Only moderate yields could be obtained, and the maximum turnover number was 51, mainly because of precipitation of palladium metal. The probable mechanism of the reaction is discussed. |
