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.

Paragraph 0068-0071, (2016/10/10)
The invention discloses a method for preparing 2-sulfur cyano acetophenone derivatives. The method for preparing the 2-sulfur cyano acetophenone derivatives comprises the following steps: dissolving styrene derivatives and ammonium thiocyanate in a solvent, and reacting at 20-30 DEG C to obtain 2-sulfur cyano acetophenone derivatives. According to the method for preparing the 2-sulfur cyano acetophenone derivatives, the styrene derivatives are taken as starting materials; the raw materials are easily available and various in type; products prepared by the method have various in type, can be directly used and can also be used for other further reactions; meanwhile, the method is mild in reaction conditions and simple in reaction operation and post-processing process; an accelerant does not need to be added; the production process meets the green and chemical requirements, is relatively high in yield and is suitable for large-scale production.

A facile and efficient protocol of oxythiocyanation of styrenes with ammonium thiocyanate has been developed. The reaction proceeded at room temperature using oxygen as sole oxidant to afford the α-oxothiocyanates via radical pathway in moderate to good yields. This method is straightforward, green and cost-effective, requires no catalyst and additives.
