Synthetic compounds that release carbon monoxide (CO) in controlled amounts are of current interest for both biological and synthetic applications. An area that has seen little development is that of solid compounds that exhibit visible light-induced CO release reactivity. This presentation will focus on the chemistry of zinc bis-flavonolato derivatives of an extended flavonol motif. These compounds undergo the same quantitative, visible light-induced CO release reaction in solution or in the solid state. Results of studies of the use of a Zn(flavonolato)2 derivative as an in situ CO release agent for aerobic oxidative palladium-catalyzed alkoxycarbonylation to produce esters in ethanol will be reported.
