在手性膦-指示钯（ii）配合物的存在下，在甲醇水溶液中进行了三芳基铋与环和非环烯酮的1,4加成反应。（S，S）-chiraphos或（S，S）- dipapp的钯配合物产生了光学活性高达95% ee的β -芳基酮。
A 1,4-addition of triarylbismuths to cyclic and acyclic enones was carried out in aqueous methanol in the presence of a chiral phosphine-dicationic palladium(ii) complex. Palladium complexes of (S,S)-chiraphos or (S,S)-dipamp gave optically active beta-arylketones of up to 95% ee.
