Decarboxylative C–C and C–N Bond Formation via Ligand-Accelerated Iron Photocatalysis

Through iron photocatalysis, a mild and effective protocol for the decarboxylative C–C and C–N bond formation has been achieved. The carboxylic acids readily underwent radical decarboxylation in the presence of Fe2(SO4)3 and di-(2-picolyl)amine with visible light irradiation. The resultant alkyl radicals then reacted with Michael acceptors or azodicarboxylates to furnish the adducts.
