An efficient and general two-step halogenation procedure to prepare diethyl α,α-bromofluorophosphonates was described, which included bromination by PPh3, 2,3-dichloro-5,6-dicyanobenzquinone (DDQ) and n-Bu4NBr, and electrophilic fluorination by N-fluorobisbenzenesulfonimide (NFSI). Both aromatic and aliphatic α,α-bromofluorophosphonates could be prepared by this method.
