一种含有三酮配体和桥联双膦配体的双金属钯(II)配合物，通过直接空气氧化将醋酸中的烯烃氧化为烯丙基乙酸酯，这不需要中间氧化还原体系。当双膦为手性时，发生不对称反应，对环烯烃的对映体选择性在52%到78%之间。(C)2002爱思唯尔科学有限公司。保留所有权利。
A bimetallic palladium(II) complex containing a triketone ligand and a bridging diphosphine ligand oxidizes olefins in acetic acid to allylic acetates by a direct air oxidation, which does not require intermediate redox systems. When the diphosphine is chiral, an asymmetric reaction occurs which gives enantioselectivities between 52 and 78% for cyclic olefins. (C) 2002 Elsevier Science Ltd. All rights reserved.
