A new catalyst platform for C(sp3)−H bond functionalization has been discovered. “Sandwich” diimine-copper(I) complexes catalyze reactions of alkane, ether, and amine C−H bonds with a large panel of diazo compounds. Additionally, the first metal-catalyzed C(sp3)−H methylation by CH2N2 is disclosed. The electrophilicity and extreme steric bulk of these catalysts are likely reasons for their efficiency
