Abstract	Neopentyl arenesulfonates reacted with primary alkylmagnesium halides in the presence of (PPh₃)₂NiCl₂ to produce the corresponding alkylarenes. The efficiency of this coupling reaction considerably depends on the nature of catalyst and solvent. Highest yield was obtained by using three equivalents of Grignard reagent to a mixture of (PPh₃)₂NiCl₂ and arenesulfonate in refluxing Et₂O. This reaction represents a novel method allowing the efficient and creative substitution of sulfur-containing groups in aromatic compounds. It also shows that the alkyloxysulfonyl group might be a suitable alternative to halides and triflate in some circumstances.
