One-pot synthesis of (ethoxycarbonyl)difluoromethylthioethers from thiocyanate sodium and ethyl 2-(trimethylsilyl)-2,2-difluoroacetate (TMS-CF2CO2Et)

An efficient one-pot cascade methodology for the synthesis of (ethoxycarbonyl)difluoromethyl thioethers is described. Benzyl, allyl, alkyl halides or diazonium salts as the starting materials together with thiocyanate sodium and TMS-CF2CO2Et in the presence of CsF or NaOAc afford a variety of the fluoroalkylthiolated products in moderate to good yields.

Process for the production of chloromethyl thiocyanate

Chloromethyl thiocyanate is prepared by reacting bromochloromethane with an alkali or alkaline earth thiocyanate or with ammonium thiocyanate in the presence of water and an onium salt as a catalyst.
