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

Diastereoselective bromodifluoromethylation of chiral imide enolates via insertion of difluorocarbene
The bromodifluoromethylation of lithium enolates of chiral N-acyloxazolidinones via the insertion of difluorocarbene proceeds with good diastereomeric excess (68–92% de).
Reaction of CH2Br2 with CBr2F2 and alkenes 1a–e in the presence of 60% aqueous KOH and tetrabutylammonium hydrogensulphate as a catalyst affords gem-difluorocyclopropanes 2a–e.
