Takeda, Sunao published the artcileα,α-Gem-difluorination of α-(alkylthio)acetophenone derivatives with N-fluoropyridinium salts, HPLC of Formula: 107263-95-6, the publication is Chemical & Pharmaceutical Bulletin (2000), 48(7), 1097-1100, database is CAplus and MEDLINE.
The α,α-gem-difluorination of 2′,4′-difluoro-α-(methylthio)acetophenone with N-fluoropyridinium salts gave 2′,4′,α,α-tetrafluoro-α-(methylthio)acetophenone. This reaction was accelerated by the addition of zinc chloride, zinc bromide or anhydrous iron(III) chloride, and higher yields than the reaction without additives were obtained. The gem-difluorination reaction using FP-T300 in the presence of zinc bromide was applicable to other α-(alkylthio)acetophenone derivatives
