An iron-catalyzed carbenoid insertion into C–H bonds of alkanes was developed with high activity (turnover numbers up to 690 in a gram-scale experiment) and chemoselectivity. This non-heme iron-catalyzed C(sp3)–H insertion reaction provides an efficient strategy for C–H functionalization.

Thermally induced reactions of donor/acceptor diazo compounds generate carbene intermediates capable of C–H functionalization reactions of alkanes. A variety of C–H insertion products were obtained in moderate to good yields and in certain cases with good site selectivity, favoring the functionalization of the more highly substituted C–H bond.
