compounds and good nucleophiles as substrates. Herein, we developed a copper‐catalyzedcarbonylative transformation of cycloalkanes and amides. Imides were prepared in good yields by carbonylation of a C(sp3)−H bond of the cycloalkane with the amides acting as weak nucleophiles. Notably, this is the first report of copper‐catalyzedcarbonylative C−H activation.

A metal-free radical oxidative carbonylation of alkanes is demonstrated, yielding esters and imides by means of di-tert-butylperoxide as oxidant. Various alkanes, alcohols and amides were compatible in this system generating the desired carbonyl products in up to 86% yields. We proposed a plausible radical cross-coupling process based on the preliminary mechanistic studies.
