The solvolysis rates and products of several 7-anti-substituted 2-endo-norbornyl p-toluenesulfonates 11 have been determined and compared with those of the previously reported 6-exo-substituted 2-exo-norbornyl p-toluenesulfonates 1. Although the number of bonds between the substituent and the reaction site is the same in the two series, the inductive effect of the substitutents is transmitted far more
溶剂分解率和产品数7防取代2-内-norbornyl p -toluenesulfonates 11已经确定,并与先前报道的6-相比外取代2-外-norbornyl p -toluenesulfonates 1.虽然数量在两个系列中,取代基和反应位点之间的键数相同,在6- exo -2- exo- series 1中,取代基的诱导作用要比在7- anti -2- endo中传递的强得多。系列11 ;也就是说,它们的电感差异很大。结论是,通过空间诱导涉及带有取代基的C原子到C(2)处的初始阳离子中心的分级桥连,并且这涉及到不同的桥连应变。然后可以将未取代的2-外-和2-内-降冰片基衍生物的不同反应性归因于立体电子效应。
