摘要: A new porphyrin-based porous organic polymer (POP) with BET surface area ranging from 780 to 880 m(2)/g was synthesized in free-base form via the reaction of meso-tetrakis(pentafluorophenyl) porphyrin and a rigid trigonal building block, hexahydroxytriphenylene. The material then metallated Fe(III) imparting activity for Lewis acid catalysis (regioselective methanolysis ring-opening styrene oxide), oxidative cyclization (conversion bis(2-hydroxy-1-naphthyl)methanes corresponding spirodienone), tandem catalytic processes: an situ oxidation-cyclic aminal formation-oxidation sequence, which selectively converts benzyl alcohol 2-phenyl-quinazolin-4(3H)-one. Notably, catalyst is readily recoverable reusable, little loss activity.
