yridines at the lower rim position of the benzene ring was achieved conveniently from their cross-coupling reaction with both aliphaticalcohols including chiral primary and secondaryalcohols and phenol derivatives through the Cu(ClO4)2-mediated aerobic aryl C–H activation, which gave structurally well-defined aryl–Cu(III) intermediates and a subsequent C–O bond formationreaction under very mild
