Abstract

An efficient electrophilic fluorination of secondary phosphine oxides with Selectfluor provides direct access to phosphoric fluorides in good yield under mild conditions. In addition, one-pot P-O bond construction is achieved in the presence of water or alcohols to provide phosphinic acids or phosphinates.
