资源简介：
Regiospecific halogenation of azacalix[1]arene[3]pyridines at the lower rim position of the benzene ring was achieved from their cross-coupling reaction with cost-effective alkali metal halides through the Cu(ClO4)2-mediated aerobic aryl C–H activation, which gave structurally well-defined aryl-Cu(III) intermediates, and a subsequent C–X bond formation reaction under very mild conditions.
