  A new synthesis of trifluoromethyl sulfides utilizing thiocyanates and fluoroform

  摘要：

  Fluoroform is a potent greenhouse gas which should not be released to the atmosphere. Large amounts of it are stored and wait for new and useful reactions to be based on it. One such general reaction that is described in this paper is its use in preparation of the important organic trifluoromethyl sulfides. Aliphatic, aromatic and heterocyclic thiocyanates are easy to prepare. They were reacted with fluoroform-based CuCF3 to form the corresponding (trifluoromethyl)thio derivatives.

  A general and convenient copper-mediated trifluoromethylthiolation of primary and secondary alkyl halides was described. Variation of the solvent, additives and time allowed optimization of the reaction. A wide range of alkyl halides were explored to give a set of alkyl trifluoromethyl thioethers in moderate to excellent yields. A variety of functional groups, including ethers, thioether, esters, nitriles, amides, and ketal groups, were well tolerated in the electrophilic partner.

  The trifluoromethylthio group is of rising interest in medicinal, agrochemical, and materials chemistry. Although several strategies for the introduction of this functional group have been described, new synthetic methods are needed. A novel ionic liquid, 1-n-butyl-3-methylimidazolium trifluoromethylthiolate, has been developed and is herein reported as an efficient and recyclable in situ generated

  catalysis for the selective activation of otherwise unactivated C(sp3)-H bonds, followed by their trifluoromethylthiolation, which has high potential as a late-stage functionalization tool. The generality of this method is exhibited through incorporation of the trifluoromethylthio group in a large number of C(sp3)-H bonds with high selectivity without the need for an excess of valuable substrate.
