The reaction between m-chloroperbenzoic acid and phosphabicyclic phosphine oxides (e.g. 8-phenyl-8-oxo-8-phosphabicyclo[3.2.1]oct-6-ene) was investigated and the structure and stereochemistry of the compounds elucidated. It could be shown that compounds possessing the allyl-P(O) R(or Ar) site, in which the double bond is hindered enough to prevent a usual epoxidation, are oxidised by the peracid to
之间反应米氯过苯甲酸和phosphabicyclic膦氧化物的结构和立体化学的化合物的(例如,8-苯基-8-氧代-8-磷杂[3.2.1]辛-6-烯)进行了研究阐明。可以证明,具有烯丙基-P(O)R(或Ar)位点的化合物被过酸氧化为相应的次膦酸酯,其中双键受阻足以阻止通常的环氧化。此外,当仍使所得化合物张紧时,膦酸酯不稳定。所建议的氧化机理是类似于已知酮的Bayer-Villiger氧化的过程。
