Recent progress of decacarbonyldimanganese catalysis

Decacarbonyldimanganese (Mn2(CO)10), one of the most long-standing organometallic reagents, bears a weak Mn-Mn bond, which occurs a homo-cleavage feasibly under heating or light-irritation, delivering an active manganese-centered radical. This highly reactive metallic radical could activate the Si-H bond, C-halogen bond, N-halogen bond, S-halogen bond, and O=O bond, generating corresponding Mn species and Si, C, N, S, and O radicals. This wonderful reactivity enables an extensive utilization of this dimeric manganese in catalytic atom-transfer reactions and oxidation reactions. In this review, we offer a comprehensive review of this growing area in recent decades. Critical comparisons and mechanism analyses are provided, along with personal perspectives for future studies.
