kinetic study has been conducted on the reaction of (arylthio)trimethylstannanes with 1-aryl-1-bromoethanes. The reaction of the arylbromoethane bearing an electron-donating substituent was found involving unimolecular ionization of the arylbromoethane. The other reactions, however, were found to be second-order reactions. The nature of the second-order reactions was shifted from one involving unimolecular
对(芳硫基)三甲基锡烷与 1-芳基-1-溴乙烷的反应进行了动力学研究。发现带有给电子取代基的芳基溴乙烷的反应涉及芳基溴乙烷的单分子电离。然而,发现其他反应是二级反应。根据芳基溴乙烷上取代基的吸电子性质,二级反应的性质从涉及单分子电离作为次要过程的反应转变为明确的双分子亲核反应。
