Bifunctionality of dirhodium tetracarboxylates in metallaphotocatalysis.

ABSTRACT: Metallaphotocatalysis has been recognized as a pivotal catalysis enabling new reactivities. Traditional metallaphotocatalysis often requires two or more separate catalysts and exhibits flaw in cost and substrate-tolerance, thus representing an await-to-solve issue in catalysis. We herein realize metallaphotocatalysis with a bifunctional dirhodium tetracarboxylate ([Rh₂]) alone. The [Rh₂] shows an photocatalytic activity of promoting singlet oxygen (¹O₂) oxidation. By harnessing its photocatalytic activity, the [Rh₂] catalyzes a photochemical cascade reaction (PCR) via combination of carbenoid chemistry and ¹O₂ chemistry. The PCR is characterized by high atom-efficiency, excellent stereoselectivities, mild conditio
