Abstract
|
A new porphyrin-based porous organic polymer (POP) with BET surface area ranging from 780 to 880 m2/g was synthesized in free-base form via the reaction of meso-tetrakis(pentafluorophenyl) porphyrin and a rigid trigonal building block, hexahydroxytriphenylene. The material was then metallated with Fe(III) imparting activity for Lewis acid catalysis (regioselective methanolysis ringopening of styrene oxide), oxidative cyclization catalysis (conversion of bis(2-hydroxy-1-naphthyl) methanes to the corresponding spirodienone), and a tandem catalytic processes: an in situ oxidationcyclic aminal formation-oxidation sequence, which selectively converts benzyl alcohol to 2-phenylquinazolin- 4(3H)-one. Notably, the catalyst is readily recoverable and reusable, with little loss in catalytic activity.
