The synthesis of salts and esters of perfluorinated dithio- and thiocarboxylic acids from carbon disulfide and carbonyl sulfide reacting with RFSiMe3/F−
摘要:
Trimethyl(perfluoroalkyl)silanes react with carbonyl sulfide and carbon disulfide in the presence of fluoride ion to give salts and, after alkylation of the latter, esters of the corresponding perfluorinated thio- and dithiocarboxylic acids. (C) 2004 Elsevier B.V. All rights reserved.

reaction, "thiophilic addition of an organomagnesium reagent onto dithioester-beta-elimination of fluoride-[3,3] sigmatropic rearrangement", provides the product of formal regiospecific substitution of a fluorine atom by an allyl group. This mild and versatile methodology was applied to the synthesis of various alpha-allylic and alpha,alpha-bis(allylic) alpha-trifluoromethyl dithioesters.
