The electroreduction of a 1:1-mixture of 2-bromobenzyl 2,2-dimethylpropanedithioate and 2-bromo-5-methylbenzyl 2,2-dimethylbutanedithioate led to a mixture of 2-Tert-butylbenzo[b]thiophene, 2-Tert-Amylbenzo[b]thiophene, 2-Tert-butyl-5-methylbenzo[b]thioph

(Chemical Equation Presented) When the counterion counts: The yield and selectivity of the title transformation of benzoic acid derivatives were improved greatly by using tetraalkyl ammonium salts as additives (see scheme; monoselectivity: 5:1-18:1). These effects are attributed to the influence of counter cations. The halogenated products are versatile intermediates for the construction of substituted aromatic compounds. DMF=N,N-dimethylformamide.
