Visible light photocatalysis of [2+2] styrene cycloadditions by energy transfer

Angew Chem Int Ed Engl. 2012 Oct 8;51(41):10329-32. doi: 10.1002/anie.201204835. Epub 2012 Sep 10.

Abstract

Hip to be square: Styrenes participate in [2+2] cycloadditions upon irradiation with visible light in the presence of an iridium(III) polypyridyl complex. In contrast to previous reports of visible light photoredox catalysis, the mechanism of this process involves photosensitization by energy transfer and not electron transfer.
