PREPARATION OF HALO-F-METHANES VIA POTASSIUM FLUORIDE-HALOGEN CLEAVAGE OF HALO-F-METHYLPHOSPHONIUM SALTS
Burton, D. J.,Shin-Ya, S.,Kesling, H.S.
, p. 89 - 98 (1982)
Treatment of halo-F-methylphosphonium salts with potassium fluoride and halogen (I2, Br2, ICl, IBr) gives modest yields of halo-F-methanes.This method of preparation augments the classical Hunsdiecker approach to these materials.
