Advances in Organic and Organic-Inorganic Hybrid Polymeric Supports for Catalytic Applications

Abstract

Abstract:In this review, the most recent advances (2014)(2015)(2016) on the synthesis of new polymer-supported catalysts are reported, focusing the attention on the synthetic strategies developed for their preparation. The polymer-supported catalysts examined will be organic-based polymers and organic-inorganic hybrids and will include, among others, polystyrenes, poly-ionic liquids, chiral ionic polymers, dendrimers, carbon nanotubes, as well as silica and halloysite-based catalysts. Selected examples will show the synthesis and application in the field of organocatalysis and metal-based catalysis both for non-asymmetric and asymmetric transformations.

Chiral catalysts immobilized on achiral polymers: effect of the polymer support on the performance of the catalyst

“…[13][14][15] Since the early developments in homogeneous asymmetric catalysts, their immobilisation onto inorganic or organic supports has been targeted. 16,17 The supported versions of reagents and catalysts present, ideally, several distinct advantages in terms of their practical use, relative to their homogeneous analogues. 18,19 In particular, we should mention the facilitation of the work up, with the possibility of easy separation and recovery of the supported systems from the reaction mixture and the concomitant facilitation of recycling.…”

Superparamagnetic Fe3O4@Alginate supported L‐arginine as a powerful hybrid inorganic–organic nanocatalyst for the one‐pot synthesis of pyrazole derivatives

“…[2][3][4][5] The functionalization of inorganic magnetic nanoparticles coated with organic polymer shells represents one of the most appropriate and current methods for manufacturing magnetic polymer/inorganic nano-hybrids with promising applications in heterogeneous catalysis because of their ease of separation and good reusability. [6,7] It is important to underline that, today, more emphasis is placed on the development of heterogeneous catalysts based on biopolymers. In this regard, polysaccharides which are large macromolecules available from natural sources with structural diversity and biocompatibility are very attractive candidates.…”

Assembly immobilized palladium(0) on carboxymethylcellulose/Fe3O4 hybrid: An efficient tailor‐made magnetically catalyst for the Suzuki–Miyaura couplings

“…and organic supports (such as polystyrene, polyaniline, polyvinylpyrrolidone, hydrogel, biopolymer, and so forth) have been reviewed . The design and preparation of novel hybrid catalyst with superior activities and unique potential application in catalysis have attracted extensive attention in the academic and industrial community in recent years. Although there has been some tremendous progress in this area in recent years, a number of problems still remain to be addressed.…”
