report a new method for the synthesis of acylphosphineoxides by the direct coupling of hydrogen phosphine oxides and acyl chlorides mediated by chlorosilanes. This new protocol is greener and safer, because it precludes the generation of volatile haloalkanes and the use of oxidants employed in the conventional methods. Moreover, moisture-unstable acylphosphineoxides that are difficult to prepare via the

Trimethylsilyl esters of general formula RR′POSiMe3 react in a quantitative and fully chemoselective way with sulphuryl chloridefluoride to give phosphorofluoridates RR′P(O)F of high purity under extremely mild conditions.
