A Microporous Binol‐Derived Phosphoric Acid

Abstract

Keine Verlangsamung: Ein mikroporöser wiederverwendbarer heterogener Katalysator, hergestellt aus einem von 1,1′‐Binaphthalin‐2,2′‐diol (binol) abgeleiteten Phosphorsäurechlorid, ist in verschiedenen Reaktionen genauso aktiv wie der entsprechende homogene Katalysator. Die Reaktionsgeschwindigkeiten, Ausbeuten und Enantioselektivitäten sind vergleichbar.

Preparation and adsorption performance of cross-linked porous polycarbazoles

“…Tan's group recently developed a versatile strategy for the preparation of microporous polymers by a simple one-step Friedel-Cras alkylation of aromatic monomers using formaldehyde dimethyl acetal (FDA) as an external cross-linker. 15 Using this method, microporous heterocyclic polymers 16,17 and triphenylphosphine-functionalized hypercrosslinked porous polymers 18 have been successfully prepared for gas uptake and catalyst immobilization, respectively.…”

Porous Organic Polymers: Promising Testbed for Heterogeneous Reactive Oxygen Species Mediated Photocatalysis and Nonredox CO2 Fixation

“…In this context, judicious assimilation of chiral organocatalytic building units into the POP matrix could lead to a robust, reusable heterogeneous platform for asymmetric organocatalysis. Recently, chiral phosphoric acid and chiral thiourea‐based cores have been used to develop POP‐based asymmetric catalysts [123,124] …”

Recent advances in the asymmetric reduction of imines by recycled catalyst systems

“…With the aim of delivering a polymer CPA catalyst possessing higher activity, Blechert et al synthesized a microporous BINOL-derived phosphoric acid catalyst by the oxidative coupling of monomer C17 (2,5 positions of thiophene unit). 32 The preparation of molecular catalyst and polymer catalyst is shown in Scheme 23.…”
