Our latest work exploring the combination of N-heterocyclic carbene (NHC) organocatalysis and photochemistry is now out in Tetrahedron as part of the special collection entitled "System-Oriented Development of Organocatalysis" (Editor: H. Ohmiya). In this study, acyl azolium salts of the kind formed during NHC-catalyzed reactions of carboxylic acid derivatives are shown to engage in Norrish Type II elimination reactions upon light irradiation. Moreover, in special cases, Norrish-Yang cyclizations can be observed.
