Abstract
s-Tetrazine based molecules were prepared for visible-light-driven organic transformations. The 3, 6-di (pyridin-2-yl)-1, 2, 4, 5-tetrazine (pytz) derivative shows visible light absorption and reversible one-electron reduction behavior. In the presence of pytz and aerial oxygen, aldehyde reacts with o-phenylenediamine or o-aminothiophenol under visible light irradiation at ambient temperature to produce corresponding 2-substituted ...
