One major theme of research in the Yoon lab is the development of unique chemical transformations enabled by visible light photochemistry.  A variety of transition metal photocatalysts responsive to visible light are known, and the Yoon lab has shown that their well understood photochemistry can be coupled to cycloadditions, arene oxidations, amine functionalizations, and thiol-ene reactions, among others.  An important feature of this strategy is the ability to use rational ligand modifications to tune the photophysical and electrochemical properties of the catalyst, exemplified by the complexes below.

Ruthenium(II) polypyridyl complexes promote the efficient radical cation Diels-Alder cycloaddition of electron-rich dienophiles upon irradiation with visible light. These reactions enable facile [4 + 2] cycloadditions that would be electronically mismatched under thermal conditions. Key to the success of this methodology is the ...Read More

We report that Ru(bipy)3Cl2 can serve as a visible light photocatalyst for [2+2] enone cycloadditions. A variety of aryl enones participate readily in the reaction, and the diastereoselectivity in the formation of the cyclobutane products is excellent. We propose a mechanism in which a photogenerated Ru(bipy)3+ complex promotes ...Read More
