The synthesis of a variety of new halo-F-methylphosphonates has been achieved by a Michaelis–Arbuzov type reaction between a halo-F-methane and a trialkyl phosphite. This synthesis has proved to be of wide scope and utility for the high yield preparation of a number of heretofore unknown compounds. The 1H, 19F, 13C and 31P NMR spectroscopic properties are reported in detail. The mechanism for the formation

The Michaelis-Becker reaction between diethyl sodiophosphite and either of the halofluoromethanes CF2Cl2 and CF3Br gives tetraethyl difluoromethylenebisphosphonate. By contrast, the corresponding reaction with CFCl3 gives not only diethyl dichlorofluoromethanephosphonate but also tetraethyl pyrophosphate as the major product. Diethyl dichlorofluoromethanephosphonate, readily prepared by a normal Arbusov
