Trichloroacetic acid in dimethyl sulphoxide as a source of trichloromethyl anions: formation of an adduct and substitution product with 1,3,5-trinitrobenzene
Abstract
Solutions of trichloroacetic acid in dimethyl sulphoxide generate trichloromethyl anions which can be trapped by species susceptible to nucleophilic attack, such as 1,3,5-trinitrobenzene; the procedure is preparatively useful.
