Singlet dioxygen is readily split by phosphine–boronates under mild conditions. The initially formed phosphine peroxides spontaneously rearrange by B→O migration. The resulting peroxoboronates have been structurally characterized, and their ability to undergo oxygen transfer reactions substantiated.
在温和的条件下,单线态双氧很容易被膦-硼酸酯分解。最初形成的过氧化膦通过B→O迁移自发地重排。所得到的过氧硼酸酯已经进行了结构表征,并且证实了它们进行氧转移反应的能力。
