[3+2] Photooxygenation of aryl cylopropanes via visible light photocatalysis.

Zhan Lu1, Jonathan D Parrish1, Tehshik P Yoon1.   

Abstract

We report that Ru(bpz)32+ is an excellent sensitizer for the photooxygenation of aryl cyclopropanes upon irradiation with visible light. The effectiveness of this photocatalyst enables the synthesis of a range of five-membered endoperoxides in excellent yield with quite low (0.5 mol%) catalyst loadings even when standard household light sources are utilized.
