In recent years, some X-ray structural and computational evidence has emerged for noncovalent carbon bonding (C-bond). However, evidence of C-bonds in solution is limited. Herein, from the conformational analyses of strategically designed N-methyl-N,N'-diacylhydrazines, we for the first time show that C-bonds can be modulated to control the conformational preferences of small molecules in solution
近年来,非共价碳键(C键)的X射线结构和计算证据已经出现。但是,溶液中C键的证据有限。本文中,从对策略性设计的N-甲基-N,N'-二酰基肼的构象分析中,我们首次表明可以调节C键来控制溶液中小分子的构象偏好。我们表明,异常的N(酰胺)CX非共价碳键相互作用稳定了N-甲基-N,N'-二酰基肼的反式(tc)酰胺键旋转异构体,超过了预期的反式(tt)旋转异构体。
