Synthesis and characterization of two new metal ion-binding resins. And the article contained the following:
A com. available macroreticular resin containing 73 mol % 4-vinylpyridine crosslinked with 21 mol % divinylbenzene (I) was successfully derivatized at the pyridine rings by a multi-step synthetic pathway. First-time application of reactions well established for monomeric pyridine derivatives (N-oxidation, Reissert-Henze cyanation, and 2-oxazoline formation) to a copolymer of 4-vinylpyridine furnished the new functionalized resins, I-4-vinyl-2-(4,4-dimethyl-2-oxazolinyl)pyridine copolymer (II) and I-4-vinyl-2-pyridinecarboxylic acid copolymer (III) in yields for functionalization of pyridine residues of 58% in each case. Estimates of formation constants for 1:1 complexes of Cu(II) and Ni(II) ions with the oxazolinylpyridine and 2-pyridinecarboxylate residues of the new resins were obtained with a competitive spectrophotometric method. The formation constants for the Cu(II)- and Ni(II)-II complexes were 107.7 M-1 for Cu(II) and 105.8 M-1 for Ni(II). The formation constants for the Cu(II) and Ni(II) complexes with III were 108.8 and 105.5 M-1, resp. The experimental process involved the reaction of 2-(4,5-Dihydro-4,4-dimethyl-2-oxazolyl)pyridine(cas: 109660-12-0).Synthetic Route of 109660-12-0
