“…Moreover, H + carrying cation-exchange resins can be used for acid catalyzed organic reactions [401][402]. On the other hand, non-ionic porous resins are also used in catalysis [403][404]. The catalyst is either a covalently attached organic molecule [405] or a metal that is chelated to the resin thanks to the electron donating ligands [406][407][408][409][410].…”

“…Polymer supports, also referred to as polymeric reagents and functional polymers, are beaded or microspherical polymer products with a particle size range of about 5–500 μm [1–3]. They have been used in an increasingly large number of applications, for example, separation and purification, catalysis, drug delivery, solid phase organic synthesis, microencapsulation of phase change materials and templates for nanoparticle growth [4–10].…”

Cross-linked polymer beads with different cross-linking agent loading were prepared by carrying out cross-linking suspension copolymerization of styrene-divinylbenzene (St- DVB) monomers using guar gum (GG) and xanthan gum (XG) from bioresources as eco-friendly suspension biopolymer stabilizers in the presence of non reactive diluents. The effects of GG and XG as suspension biostabilizers on the characteristics of the styrene copolymer beads were investigated regarding thermal properties, porosity characteristics, solvent swelling ratio, and surface morphologies using TGA, DSC, XRD, SEM, BET analyses. Spherical and regular beads with smooth surface were produced and the average particle size was in the range 170–290 μm (50–80 mesh size). The porosity characteristics of the produced beads including surface area and pore volume were in range 0.45 m2/g and 32–45 ml/g, respectively. Overall, the present article provided a novel route to prepare cross-linked polystyrene copolymer beads with tunable porosity suitable for catalyst support.

“…Since schematic and graphical representations of aminomethylated NovaPeg and ChemMatrix resins in catalogues 6 and papers 4,7 describing the benefits of their use in difficult peptide synthesis, often omit to depict residual free hydroxyl functionalities (see Figure 1), it is important to realize that they are present and might interfere with some of the processes carried out on the resin. For the capping procedure: 6 eq acetic acid anhydride and 6 eq DIPEA were added to the solid support in DMF.…”

During solid phase peptide synthesis on novel aminomethyl-PEG-based resins, undesired coloration of resins was observed during color tests due to the presence of left-over alcohol functionalities in the base resin. These can participate in ongoing reactions and lead to unexplicable outcomes, if not taken into consideration.Leave this area blank for abstract info. Abstract-Recently developed PEG-based resins have been shown to markedly improve the quality of the synthesis in case of so-called 'difficult' peptide sequences. Difficult coupling reactions further require sensitive color tests for amines in the assessment of the completeness of coupling. We here describe how the use of PEG-based resins in combination with one of the more sensitive color tests in SPPS can lead to severe misinterpretation and unnecessary delays during solid phase peptide synthesis due to the presence of 'nondeclared' free hydroxyl functionalities in aminomethyl-PEG-based resins F-31 color test uncovers 'hidden' alcohol functionalities in PEG-based resins for solid phase peptide synthesis
