Neopentyl arenesulfonates were reacted with methyl and primary alkylmagnesium bromides in the presence of dppeNiCl2, via the nucleophilic aromatic substitution of neopentyloxysulfonyl groups by the primary alkyl nucleophiles, to produce the corresponding alkylarenes in good yields. This result shows that the alkyloxysulfonyl group might be a suitable alternative to halides and triflate in some circumstances
在dppeNiCl 2存在下,通过新戊氧基氧磺酰基被伯烷基亲核试剂的亲核芳族取代,使新戊基芳烃磺酸盐与甲基和伯烷基溴化镁反应,以高收率生产相应的烷基芳烃。该结果表明,在某些情况下,烷氧基磺酰基可能是卤化物和三氟甲磺酸酯的合适替代物。
