  Isolation and Low-Temperature X-ray Analysis of Intramolecular Triarylmethane−Triarylmethylium Complex:  Preference for a C−H-Bridged Unsymmetric Structure Exhibiting a Facile 1,5-Hydride Shift and Charge-Transfer Interaction

  摘要：

  The intramolecular triarylmethane-methylium complex with an averaged C2v-symmetry was successfully generated by N-methylation of the acridine-acridan hybrid. Theoretical calculation and VT-NMR analyses in solution indicate the unsymmetric geometry for the three-center bond, which was finally confirmed crystallographically. Significant degree of CT interaction is induced through the very short C-H...C+ contact.

  um complexes with a naphthalene-1,8-diyl-type skeleton have been achieved. These bridged cations prefer a C--H localized structure both in solution and in the solid state. The bridging hydrogen undergoes a facile intramolecular 1,5-hydride shift from one carbon to another in solution. The C--H delocalized geometry is suggested to be the transition-state structure of the degenerate rearrangement. Charge-transfer

  具有萘-1,8-二基型骨架的分子内三芳基甲烷-三芳基甲基鎓配合物的分离和低温X射线分析已实现。这些桥连的阳离子在溶液和固态中均更倾向于CH局部结构。桥接的氢在溶液中经历从一个碳到另一个碳的容易的分子内1，5-氢化物转变。建议将CH杂化的几何结构是简并重排的过渡态结构。从三芳基甲烷到三芳基甲基鎓单元的电荷转移相互作用在电子光谱中是明显的。这种相互作用稳定了目前的阳离子。对布朗斯台德酸的低反应性表明，这些物质不是1,1,2,2-四芳基萘衍生物在酸辅助的长键裂解中的反应中间体。

  Acenapthalene, pyracene, and dihydropyracylene attached to two units of spiroacridan are a novel class of hexaphenylethane (HPE) derivatives that have an ultralong Csp3-Csp3 bond (1.77-1.70 A). These sterically challenged molecules were cleanly prepared by C-C bond formation through two-electron reduction from the less-hindered dications. These ultralong bonds were realized based on several molecular-design

  连接到螺菌oa啶两个单元上的庚烯，并四苯和二氢次萘并茂是具有超长Csp3-Csp3键（1.77-1.70 A）的新型六苯基乙烷（HPE）衍生物。这些空间挑战的分子是通过从较不受阻碍的指示通过双电子还原形成CC键来干净地制备的。这些超长键是基于几种分子设计概念而实现的，这些概念包括通过融合或桥接HPE分子中的芳基，通过“多重钳制”增强“前应变”。这些超长键的长度及其与构象的关系（扭转角）也通过理论计算得到了验证。
