An efficient catalytic system for the direct intermolecular α-arylation of acetamide derivatives with aryl chlorides is presented. Chemoselectivities up to 10:1 in the mono- and diarylation of acetamides were achieved by careful selection of bases, solvents, and stoichiometry. Bis-arylated amides were prepared in up to 95% yield.
本文报道了一种用于酰胺衍生物与芳基氯的直接分子间α-芳基化的高效催化体系。通过仔细选择碱、溶剂和化学计量比，可以实现酰胺的单芳基化和二芳基化的化学选择性达到 10:1。双芳基化酰胺的产率高达 95%。
