Palladium-Catalysed Direct Arylation of Heteroaromatics Using Unprotected Iodoanilines with Inhibition of the Amination Reaction
摘要:
The palladium-catalysed direct arylation of heteroaromatics with unprotected iodoanilines proceeds in moderate to high yields using only 1 mol% Pd(OAc)(2) as the catalyst and potassium acetate as the base. No amination reaction was observed under these conditions. A wide variety of heteroarenes have been successfully employed.
