benzyl carbocations was investigated using the novel technique for comparing the stability of carbocations in solution developed by using a simple CSI reaction with various ethers. The p-methoxycinnamyl carbocation was the most stable in our reaction system and the next stable carbocation was the p-methoxybenzyl carbocation. The stability of the other carbocations decreased with methacryl, t-butyl, cinnamyl
使用新颖的技术研究了各种烷基,烯丙基和苄基碳阳离子的稳定性顺序,用于比较通过使用简单的CSI反应与各种醚开发的溶液中碳阳离子的稳定性。该p -methoxycinnamyl碳正离子是我们的反应体系中最稳定,下一个稳定的碳正离子是p甲氧基苄基碳正离子。其他碳正离子的稳定性按甲基丙烯酸,叔丁基,肉桂基,丙烯酸,苄基,2°和烯丙基碳正离子的顺序降低。
