This low cost diethyl bromodifluoromethylphosphonate is supplied by many famous chemical companies. It may be easily prepared by the procedure of Burton and Flynn in excellent yield (>95, using nearly equivalent amounts of triethyl phosphite and dibromofluoromethane a precursor of difluorocarbene itself, Curiously, this version of Michaelis-Arbuzov reaction also involves a difluorocarbene as an unstable intermediate. For the synthesis of diethyl bromodifluoromethylphosphonate see also

In the hydrolysis of difluorocarbene, the hydroxide ion initially reacts with this unstable intermediate to form difluoromethanol, which eventually undergoes an elimination of HF followed by further hydrolysis to give fluoride and formate salts.{A figure is presented}
