The trifluoromethanethiolate anion may be generated in situ by the reaction of thiophosgene with potassium fluoride in acetonitrile. This system is used to prepare trifluoromethyl arylsulfides from activated fluoro- and chloroaromatic substrates via nucleophilic substitution.

Reaction of potassium fluoride or tetramethylammonium fluoride with thiophosgene leads to the formation of a nucleophilic source of trifluoromethanethiolate, suitable for the preparation of trifluoromethyl aryl sulfides from activated haloaromatics. Analysis of the byproducts in the system demonstrates that complex molecules with up to C-4 chains may be formed by the reaction of fluoride salts with thiophosgene. (C) 1999 Elsevier Science S.A.
