Alkali metal salts of perfluorinated complex anions were used to fluorinate a few selected organochlorophosphorus compounds in the presence and absence of a multifunctional etheral solvent. Together with oxidative products, low to moderate yields of the desired monofluorinated products were obtained.
A novel and efficient electrophilicfluorination 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

Direct conversion of phosphorus(V) chlorides to the corresponding phosphorus(V) fluorides was achieved utilizing a solid-supportedreagent. The phosphorus(V) fluorides were straightforwardly synthesized and efficiently isolated in very good yields.
