Laser flash photolysis studies on α-methylbenzylchlorodiazirine, n-propylchlorodiazirine, and isopropylchlorodiazirine have been carried out at low temperatures, ranging from 170 to 230 K. The present results, together with those previously obtained with benzylchlorodiazirine and methylchlorodiazirine, provide a direct measurement of the “by-stander effect” of alkyl substituents on the C atom in the
已在 170 至 230 K 的低温下对 α-甲基苄基氯二氮嗪、正丙基氯二氮嗪和异丙基氯二氮嗪进行了激光闪光光解研究。目前的结果,连同之前用苄基氯二氮嗪和甲基氯二氮嗪获得的结果,提供了对卡宾中心 α 位 C 原子上的烷基取代基的“旁观者效应”。已经测量了 α-甲基苄基氯卡宾和四甲基乙烯在异辛烷和甲基环己烷中的分子间反应,但表明该反应太慢,无法在高粘度十氢化萘溶剂中通过 LFP 进行测量。
