Major examples of the reactivation chain polymerization include the oxidative polymerization of aniline and probably other aromatic monomers, living radical polymerization, and biological polymerization for the synthesis of nucleic acids and proteins. 再活化链式聚合主要例子包括苯胺和或许其它芳香族单体的氧化聚合,活性自由基聚合,以及核酸和蛋白质合成中的生物聚合。
An ethyl acetate extract of Hengshun aromatic vinegar ( HE) exerted a weak radical scavenging activity, and the main components were phenolic and acidic compounds. 恒顺香醋乙酸乙酯萃取物具有弱自由基清除活性,主要清除活性成分为酚性和酸性化合物。
In this paper, we carefully studied the Mannich reaction between ketones and aromatic imines induced by radical cation and iodine. O-Alkylation of oximes was also achieved under radical cation induced conditions. 本论文研究了在自由基正离子诱导以及碘催化下酮类化合物与芳香亚胺的Mannich反应;同时,还研究了自由基正离子诱导肟类化合物的O-烷基化反应。
Some aromatic products were formed after the aliphatic chain was attacked by hydroxyl radical, and then were broken up into fatty compounds through the benzene ring, such as formic acid, acetic acid and acetaldehyde. 当·OH自由基攻击脂肪链时形成一些芳香类中间产物,并进一步通过苯环破裂形成脂肪化合物如甲酸,乙酸和乙醛的反应等。
Furthermore, we expanded this method to the composition of aromatic esters by radical C-O coupling reaction. 同时我们将该方法扩展到铜催化8-羟基喹啉与芳香醛通过自由基C-O偶联反应合成芳香酸-8-喹啉酯类化合物。
