Improved Carbon-Carbon Linking by Controlled Copper Catalysis

Treatment of RO3SC6H4Me-4 with R1MgBr in THF over Li2CuCl4 at -78 Deg with slowly raising the temp. to room temp. gave, in good yields, the derivs. RR1 (R = e.g. Et, Ph, cyclohexyl, or octyl; R1 = Et, CMe3, Ph, cyclohexyl). [on SciFinder (R)]
