Although the reaction between hydrogen fluoride and phosphoric acid is reversible, substantial conversion to phosphorofluoridic acid can be obtained by heating phosphorus pentoxide with 69% hydrofluoridic acid (5.264). Sodium phosphorofluoridate is formed in 80% yield if Graham s salt is heated with sodium fluoride for a brief period (sodium trimetaphosphate may also be used) (5.265).

Phosphonate analogues of nucleotides continue to attract attention. S -Hydrogen-phosphonates and 5 -methylphosphonates of various anti-HIV nucleosides have been made, and the H-phosphonates from AZT and 3 -deoxy-3 -fluorothymidine were highly active. 5 -Fluoro-methyl- and -difluoromethyl-phosphonatcs have been prepared from d4T,26 AZT,264,265 gnj various other nucleosides and deoxynucleosides,265 and phosphonates 199 (n = 1,2) were prepared from the 5 -bis(TMS)phosphite by Arbusov or Michael reaction. The non-hydrolysable analogue 200 of phosphoadenosine phosphosulfate ( active sulfate ) has been described. The 3 -phosphale was put on in the last step using trimetaphosphate, and the desired product was sq>arated from die 2 -phosphate by hplc.267...
