Palladium(II)-catalysed rearrangement of allylic acetates 5, which contain a diphenylphosphinoyl group, yields transposed acetates 6 in good yield. The reaction is mild, general for most substitution patterns, and stereospecific. The transposed acetates 6 may be hydrolysed to δ-hydroxy allylic phosphine oxides 4.
钯(II)催化的包含二苯基膦酰基的烯丙基乙酸酯5的重排以良好的产率产生转座的乙酸酯6。该反应是温和的,对于大多数取代模式是通用的,并且是立体定向的。可以将转置的乙酸酯6水解为δ-羟基烯丙基膦氧化物4。
