Sherbrook, Evan M.; Jung, Hoimin; Cho, Dasol; Baik, My-Hyun; Yoon, Tehshik P. published the artcile< Bronsted acid catalysis of photosensitized cycloadditions>, Application In Synthesis of 17082-09-6, the main research area is imidazolylpropenone preparation alkene ruthenium Bronsted acid catalyst photochem cycloaddtion; imidazolylcarbonyl cyclobutane preparation diastereoselective.
Authors showed that Bronsted acids can also modulate the reactivity of excited-state organic reactions. Bronsted acids dramatically increase the rate of Ru(bpy)32+-sensitized [2 + 2] photocycloadditions between C-cinnamoyl imidazoles and a range of electron-rich alkene reaction partners. A combination of exptl. and computational studies supported a mechanism in which the Bronsted acid co-catalyst accelerates triplet energy transfer from the excited-state [Ru*(bpy)3]2+ chromophore to the Bronsted acid activated C-cinnamoyl imidazole. Computational evidence further suggested the importance of driving force as well as geometrical reorganization, in which the protonation of the imidazole decreases the reorganization penalty during the energy transfer event.
