Kuroboshi, Manabu published the artcileA facile synthesis of difluoromethylene compounds by oxidative fluorodesulfurization of dithioacetals using tetrabutylammonium dihydrogen trifluoride and N-halo compounds, Name: 1-(Difluoromethyl)naphthalene, the publication is Synlett (1991), 909-10, database is CAplus.
Cyclic dithioacetals of aldehydes and ketones are converted into the corresponding difluoromethylene compounds with characteristic chemoselectivity by means of tetrabutylammonium dihydrogen trifluoride (I) and N-halo amides or imides (N-bromosuccinimide (II), N-iodosuccinimide and 1,3-dibromo-5,5-dimethylhydantoin) in good to excellent yield. The substrates which have an acid-sensitive functionality or other easily fluorinated functionalities give the desired products without any damage to that functionality. E.g., dithioacetal III reacts with reagents I and II in CH2Cl2 followed by treatment with sodium hydrogen sulfite to give fluoro compound IV in 94% yield.
