Novel mesoionic 2-methyl-442-(dialkylamino)-1,3-dithiol-2-ylium-4-yllphenolates have been synthesized by the heterocondensation of the 1-(4-hydroxy-3-methylphenyl)-1-oxaethan-2-yl dithiocarbamates. These compounds have been synthesized following a three step procedure that involves the reaction of 2-bromo-1-(4-hydroxy-3-methylphenyl)ethanone with various salts of dithiocarbamic acids, heterocyclocondensation under acidic conditions and treatment with aqueous NaHCO3. The regioselective side-chain bromination of 1-(4-hydroxy-3-methylphenyOethanone has been accomplished by an improved experimental procedure.
