undergo an acid-catalyzed rearrangement to form 1-chloro-D 3 -trishomocubane and was obtained by chlorosulfation of Cook-son's diketone. A possible mechanism of the reaction involving the formation of C s - and D 3 -trishomocubane nonclassical cations was proposed on the basis of a mechanistic [B3PW91/ 6-31G(d,p) and MP2/cc-pVDZ] study.
描述了获得 1-氯-C s -trishomocubane 和 1-氯-D 3 -trishomocubane 的有效合成策略。1-Chloro-C s -trishomocubane 是通过区域选择性 Diels-Alder 反应合成的,B3PW91/6-31G(d,p) 计算提供了对反应机理的合理解释。令人惊讶的是,1-氯-C s -trishomocubane 没有经过酸催化重排形成1-氯-D 3 -trishomocubane 并且是通过库克森二酮的氯硫酸化获得的。基于 [B3PW91/6-31G(d,p) 和 MP2/cc-pVDZ] 的机理研究,提出了涉及形成 C s - 和 D 3 -trishomocubane 非经典阳离子的反应的可能机制。
