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 Fe<sub>2</sub>(SO<sub>4</sub>)<sub>3 </sub>and di-(2-picolyl)amine with visible light irradiation. The resultant alkyl radicals then reacted with Michael acceptors or azodicarboxylates to furnish the adducts.<br>
