Interaction of Difluorocarbene with the Thiocyanate\nAnion: Access to a Silicon Reagent Bearing the Isothiocyanate Group

The reaction between (bromodifluoromethyl)trimethylsilane\n(TMSCF<sub>2</sub>Br) and potassium thiocyanate providing TMSCF<sub>2</sub>NCS\nis described. The process involves the interaction of difluorocarbene\nwith the nitrogen atom of the thiocyanate anion. The obtained silicon\nreagent served as a source of the fluorinated group and difluorocarbene\nin the reaction with <i>N</i>-alkyl imines, affording 2-(difluoromethylthio)-4-fluoroimidazoles.

Abstract

The reaction between (bromodifluoromethyl)trimethylsilane\n(TMSCF<sub>2</sub>Br) and potassium thiocyanate providing TMSCF<sub>2</sub>NCS\nis described. The process involves the interaction of difluorocarbene\nwith the nitrogen atom of the thiocyanate anion. The obtained silicon\nreagent served as a source of the fluorinated group and difluorocarbene\nin the reaction with <i>N</i>-alkyl imines, affording 2-(difluoromethylthio)-4-fluoroimidazoles.
