An unprecedented, straightforward photochemical platform for efficient site-selective C–H alkylation of the C7 position of the benzocore via the cross coupling between coumarins and NHPI esters, employing Ru(II) as a photocatalyst in visiblelight, has been reported. Remarkably, this transformation demonstrated broad substrate scope and good functional group compatibility. Controlled experiments and

represents the quintessential scaffold of many natural products. While C-3 alkylation is easily achievable, effective greener strategies for C-4 alkylation have been less forthcoming. Herein, we report a metal-free photoinduced deaminative strategy for C-4 alkylation of coumarins using redox activated secondary and benzylic amine derived Katritzky pyridinium salts.
