Direct introduction of -SCH3 groups into activated aromatic and hetero aromatic compounds has been achieved by reaction with dimethyldisulfide over a MnCl2-promoted K-10 montmorillonite. Unlike ZnCl2/K-10, the Mn- promoted clay appears to promote rea

A method for the direct thioalkylation of thiophene (1) and benzo[b]thiophene (7) by reaction of either heterocycle with an alkyldisulfide using a ZnCl2-modified montmorillonite clay catalyst is described. The clay-catalyzed reaction of 1 with excess

Benzylation of benzo[b]thiophene (1) with benzyl chloride catalyzed by metal-doped K-10 montmoril-lonite clays is described. Whereas ZnQ2 dissolved in either nitromethane or nitrobenzene solution promoted benzylation of (1) only very slowly and resul

A mild method for 1,2-addition of alkyl disulfides to alkenes and conjugated polyenes catalysed by MClx-promoted montmorillonite clays is reported. Alkenes undergo 1,2-trans addition affording MClx-complexed derivatives, which are readily converted t
