A novel and efficient electrophilic fluorination of secondary phosphine oxides with Selectfluor has been achieved. This transformation provides direct access to phosphoric fluorides in up to 92% yield under mild conditions. In addition, P–O bond construction via a one-pot coupling process of secondary phosphine oxides with water or alcohols in the presence of Selectfluor leads to the formation of phosphinic
已经实现了使用Selectfluor对仲膦氧化物进行新型,高效的亲电氟化。在温和条件下,这种转变可直接获得高达92%的氟化磷。此外,在Selectfluor的存在下,通过次膦氧化物与水或醇的一锅偶联过程进行的P–O键结构可导致次膦酸或次膦酸酯的形成,产率高达96%。
