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 visible light, has been reported. Remarkably, this transformation demonstrated broad substrate scope and good functional group compatibility. Controlled experiments and
