approach to gem-dialkylbenzyl heterocycles has been developed through a triflic acid-catalyzed hydroarylation of olefinic heterocycles. A broad range of substrates containing pyridine, quinoline, pyrazole, triazole and imidazole moieties are shown to be highly compatible with this method. This rapid construction of gem-dialkyl groups should be useful in the synthesis of drug-like molecules containing

The development of the oxidative cross-coupling of unreactive C(sp3)–Hbonds with (hetero)arene C(sp2)–Hbonds is considerably appealing, yet conceptually and practically challenging. Here, we disclose the rhodium-catalyzed oxidative heteroarylation of unactivated C(sp3)–Hbonds with heteroarene C(sp2)–Hbonds. This method provides a step-economic route to β-heteroarylated 2-ethylpyridine derivatives
