研究了胆碱在水溶液中活化过硫酸盐的分解动力学。此外,胆碱降解产物通过1 H NMR光谱分析,甜菜碱醛被确定为主要的氧化产物。因此,假定自由基链氧化还原机理可以解释实验结果。使用动力学建模方法成功验证了该机制。此外,发现由于衣康酸和氯化胆碱的络合物的形成,酸在水中的盐溶解度增加。最后,在胆碱盐的水溶液中由过硫酸盐引发的衣康酸的自由基聚合产生具有较高分子量和增加的多分散性的聚衣康酸。
oxidation product. Thus, radical-chain redox mechanism is postulated to explain experimental results. The mechanism was successfully verified using kinetic modeling approach. Moreover, it was found that due to formation of complex of itaconic acid and choline chloride, the salt solubility of the acid in water was increased. Finally, free-radical polymerization of itaconic acid initiated by persulfate in

liquids for discovering new reactivity, developing potent synthetic reactions, and even simplifying bioactivity evaluations. Using ILDDS, we repurposed the cycloaddition of β-carbonyl phosphonate and azide to synthesize triazolyl phosphonates that usually produced phosphonate-leaving products under the traditional conditions. And then, the repurposed cycloaddition reaction allows the access of triazolyl
