Knitting Aryl Network Polymers-Incorporated Ag Nanoparticles: A Mild and Efficient Catalyst for the Fixation of CO2 as Carboxylic Acid

Ag nanoparticles were synthesized and stabilized on a polymeric support, poly([Formula: see text]-isopropyl acrylamide-co-itaconic acid)/POSS, by simply reducing Ag[Formula: see text] ions adsorbed in the interior of the polymeric network. The prepared Ag@p(NIPAM-IA)/POSS was used as an efficient and recyclable catalyst for removal of the 4-nitrophenol (4-NP) contaminant by NaBH4-induced reduction to 4-aminophenol (4-AP) in aqueous solution. Different conditions including Ag content and amount of the nanocomposite, and also temperature of the 4-NP reduction were investigated. Also, two kinetic models, zero-order and first-order kinetics, were studied for the reduction of 4-NP to 4-AP.

Highly Efficient

A new methodology has been developed for the highly efficient diastereoselective construction of dihydrocoumarin–pyrrolidine–spirooxindole collections via a domino Michael/annulation reaction of 3-isothiocyanato oxindoles and coumarins under catalyst-free conditions. The resulting biologically important molecules bearing three pharmacophores and three contiguous stereocenters were obtained in up to 92% yield and >20:1 dr. It is noteworthy that utilization of a carboxylic acid activation/decarboxylation strategy represents an efficient approach for the domino Michael/annulation reaction of the chemically inert coumarin moiety. This protocol could expand candidate libraries, that will benefit the requirement for new bioactive molecules.
