title: Proton-assisted switching of reaction pathways of stilbene analogues brought by direct irradiation.
abstract: [figure: see text] Photochemical reaction pathways during direct irradiation of stilbene analogues (1a-1d) can be switched completely by adjusting the concentration of hydrochloric acids. Competitive ring opening and acid-catalyzed hydrolysis processes are responsible for this novel selectivity.
