Title: Triggering Thermal Cycloadditions Using Visible Light

Abstract: Rapid and catalyst-free cycloaddition systems that are activated via irradiation with visible light will be reported. Molecules that incorporate azirine,¹ o-methylbenzaldehydes² and tetrazole^3,4 moieties have been shown to undergo photo –ring opening, -enolisation and -elimination respectively. In all cases this photo-reaction produces a reactive intermediate that rapidly undergoes a thermal cycloaddition with an appropriate dipolarophile. This presentation will highlight examples of these phototriggered reactions in solution, flow and on surfaces.
