Silver-catalyzed C2-selective direct alkylation of heteroarenes with tertiary cycloalkanols

A silver-catalyzed regioselective C2-alkylation of heteroarenes with tertiary cycloalkanols under radical conditions was developed. This tandem process, which includes selective C-H activation, C(sp )-C(sp ) bond cleavage, and C(sp )-C(sp ) bond formation, affords a novel and environmentally friendly approach for the production of carbonyl-containing alkyl-substituted heteroarenes with moderate to good yields.
