O-Ethyl-S-(1,2,2,2-Tetrafluoroethyl)-Dithiocarbonate: A Convenient Reagent for the Generation and Capture of 1,2,2,2-Tetra­fluoroethyl Radicals

Abstract : The synthesis of a new fluorinated reagent O-ethyl S-(1,2,2,2-tetrafluoroethyl) carbonodithioate (xanthate) and its use for the generation and capture of the hitherto unexplored 1,2,2,2-tetrafluo­roethyl radicals is described. This reagent allows the convenient introduction of the rare CF3CHF motif onto various olefinic substrates with a high functional-group tolerance.
