Carbophilic versus thiophilic attack in the reaction of metallated aromates and heteroaromates with carbon disulfide

Copper(I) halides catalyse the formation of carbodithioates RCSSLi in the reaction of aryl- or heteroaryl-lithium reagents with carbon disulfide.Subsequent addition of methyl iodide gives the dithioesters RCSSCH3 in highh yields.Appreciable amounts of the methyl sulfides RSCH3 and tars are obtained when the reaction with CS2 is carried out in the absence of copper(I) salts, especially in the case of more basic organoalkali compounds.

S-Methyl(S-ethyl)thio(dithio)carboxinium ions were prepared by reacting methyl(ethyl) fluoride-antimony pentafluoride with carbonyl sulfide (carbon disulfide) and studied with 1H and 13C NMR spectroscopy.The ions were subsequently used in the novel carboxylation reaction of arenes to S-methyl (S-ethyl) thio(dithio)benzoates.The method was also found to be adaptable to the carboxylation of polystyrene to poly(styrenecarboxylic acid) without degradation of the polymer backbone.
