the activation and functionalization of C(sp3)–NH2 bonds in primary alkylamines remain a challenging process. In the present work, we discovered an unprecedented method to directly activate the C(sp3)–NH2 bond of primary alkylamines by a high-valent dinuclear CoIII,IV2(μ-O)2 diamond core complex. This reaction results in the installation of other functional groups such as halides and alkenes onto
