Abstract
Abstract Benzothiazole‐doped porous organic polymers ( POP‐MBTS ) were synthesized from a copolymerization reaction of 2‐(6‐(4‐vinylphenyl)pyridin‐2‐yl)benzo[ d ]thiazole with divinylbenzene. The corresponding POP‐MBTS‐Ir was obtained and fully characterized using SEM, TEM, EDS, TGA, XPS, and N 2 sorption isotherms, which disclosed that this catalyst has a high surface area, hierarchical porosity, and thermodynamic stability. Importantly, this catalyst revealed a high catalytic activity for ten different kinds of borrowing hydrogen and dehydrogenation reactions in water with a good recovery performance. Furthermore, mechanistic investigations were conducted for the synthesis of triazine derivatives.
