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

“…This classical effect was based on the higher flexibility of the functional chain and the increase in the lipophilicity of the polymer facilitating its swelling. [93][94][95][96] Dyer et al also illustrated nicely those concepts in the case of Ti-diol complexes supported using spacer-modified gel-type resins (Fig. 3).…”

“…In this regard, the introduction of long aliphatic or ether spacers favouring compatibility with a wide range of solvents [58][59][60]92,93 or the substitution of DVB by more flexible crosslinkers has been widely explored. 84 Thus, Montanari and coworkers found that the use of long aliphatic spacers (up to 10 methylene units) and low crosslinking degrees (1%) increased the corresponding activities 2-4 times in polymer-supported phase transfer catalysts.…”

Poly(vinylbenzyl chloride-co-divinyl benzene) polyHIPE monolith-supported o-hydroxynaphthaldehyde propylenediamine Schiff base ligand complex of copper(ii) ions as a catalyst for the epoxidation of cyclohexene

“…5,6 However, to improve the activity of catalysts on polymer gel-bead, spacers such as polyethylene glycol are used, but cleaving and poor loading of catalyst remained major drawbacks. 3,[12][13][14] Some efforts were made to increase the loading capacity of supports by controlling their swelling properties and improving the stability of supported catalysts. 4,15 Property modication in polymer gel-bead supports was found to be more useful in continuous ow reactors than batch reactors.…”

Diverse Supports for Immobilization of Catalysts in Continuous Flow Reactors

“…In addition, the structure of supported IL-like phases (SILLPs) could be finely tuned to adjust the catalytic efficiency of the RB-SILLP composites, leading to more active and stable systems for continuous flow synthesis of chiral cyanohydrins. [40] Vaccaro and coworkers developed a gel-type spaced crosslinked polystyrene (SPACER) resin [41,42] as support for continuous flow catalysts. Very recently, this support was applied to immobilize Pd(II)-bis(NHC) catalyst for the intramolecular C-(sp 3 )À H activation/cyclization of N-alkyl-2-bromoanilines furnishing indolines.…”
