GRAPHICAL ABSTRACT ABSTRACT A facile two-step synthesis of bisphosphine monoxides (BPMOs, with both the phosphine and phosphine oxide moieties within one molecule) from readily available Morita–Baylis–Hillman (MBH) carbonates was realized. Under the catalysis of DABCO, the MBH carbonates undergo allylic phosphorylation reaction with diphenylphosphine oxide or diethyl phosphonate to give monophosphine
图形摘要摘要实现了从容易获得的 Morita-Baylis-Hillman (MBH) 碳酸盐中轻松两步合成一氧化二膦(BPMO,在一个分子中具有膦和氧化膦部分)的方法。在DABCO的催化下,MBH碳酸酯与氧化二苯膦或膦酸二乙酯发生烯丙基磷酸化反应,得到带有活化烯烃部分的氧化单膦;随后用 HPPh2 对制备的氧化单膦进行碱催化氢膦化反应,很容易得到 BPMO。
