Abstract
Trifluoromethyl-substituted aromatic compounds were obtained by oxidative desulfurization-fluorination reaction of methyl arenedithiocarboxylates using n-Bu4N+H2F3>− and 1,3-dibromo-5,5-dimethylhydantoin (DBH). Use of N-bromosuccinimide or N-iodosuccinimide instead of DBH afforded difluoro(methylthio)methyl-substituted aromatics.
