Abstract

The outcome of photosensitized [2+2]-cycloaddition reactions of various cinnamates has been compared in different reaction media, including homogeneous organic solutions under inert conditions, degassed water, and aerated physical gels. The reactions were performed under LED blue light (lambda(max)=455 nm) irradiation and [Ir{dF(CF3)ppy}(2)(dtb-bpy)]PF6 (1.0 mol%) as photocatalyst. The processes ...
