Vinylation of a Secondary Amine Core with Calcium Carbide for Efficient Post-Modification and Access to Polymeric Materials

“…Current methods for preparing N -vinyl derivatives of secondary amines involve the vinyl exchange reaction ( Scheme 1 , route a), which requires a source of vinyl group (in most cases represented by vinyl acetate) and a metal catalyst. Enamines from nitrogenous bases [ 7 ], imidazole [ 8 ], triazoles [ 9 ], carbazole [ 10 ], and pyrrolidone [ 11 ] can be successfully obtained by this approach.…”

Synthesis, Properties, and Biological Activity of Poly(1-vinyl-1,2,4-triazole) and Silver Nanocomposites Based on It

“…Since VT is a weak base (p = 3.11), the kinetic parameters of the polymerization reaction will probably depend on the pH of a medium. For example, the authors of [ 42 ] showed that the rate of reaction is described by an extremal curve with a minimum at pH ~7. Reduction in pH from 7 to 3 leads to an increase in the rate of reaction, which is promoted by triazole ring protonation, and, accordingly, enhances electron-acceptor properties of the triazole ring and radical of a growing macromolecule.…”

Synthesis and polymerization of C-vinyl- and N-vinyl-1,2,3-triazoles

“…Relying on the propensity of the triazole cycles to generate diverse weak interactions (such as H-bonding), the same research group further investigated the influence of the polymerization medium on the kinetics of 1-vinyl-1,2,3-triazole 52 polymerization. 22 The influence of water, acetic acid and their mixtures with acetonitrile was carefully examined. It was shown that the addition of protic species has a substantial acceleration effect on the polymerization process as confirmed by the significant rise of k p /k t 0.5 from 0.54 at 60 C in acetonitrile to 2.25 and 1.94 (l/(mol s)) 0.5 respectively in water and acetic acid.…”
