Rate and product analytical results of solvolysis of benzyl azoxytosylate in 1 : 1 (v/v) trifluoroethanol: water require two product-forming routes: one involves a long-lived intermediate (formed from benzyl cations and nitrous oxide) which is trappable by dilute nucleophiles and bases; the other involves either a very short-lived intermediate (the benzyl cation) which is not capable of being intercepted
苯甲磺酸甲苯酯在1:1(v / v)三氟乙醇中的溶剂化速率和产物分析结果:水中需要两种形成产物的途径:一种涉及长寿命的中间体(由苄基阳离子和一氧化二氮形成),可以通过稀释捕集亲核试剂和碱基;另一种涉及寿命很短的中间体(苄基阳离子),它不能被溶质截留,或者根本没有中间体。
