摘要：
Autoprotolysis of the metastable acid (C6F5)(3)BOPPh2OH, prepared in situ by the reaction of the rather weak Bronsted acid Ph2PO2H with the strong Lewis acid B(C6F5)(3), gave rise to the formation of the eight-membered ring [Ph2POB(C6F5)(2)O](2) and C6F5H. The conjugate base was isolated as stable sodium crown ether salt [Na(15-crown-5)]-[Ph2PO2B(C6F5)(3)].
