    rate-equilibrium relationship. Molecular mechanics calculations (MMFF94 force field) account fairly well for the variation in the free energy difference for rotamer pairs of the di-1-adamantyl, (1-adamantyl)(tert-butyl) and di-tert-butyl derivatives, but slightly overestimate the small differences in the equilibrium constants for the three series. The calculated rotation barriers for the di-tert-butyl compounds
    将二-1-金刚烷基和(1-金刚烷基)(叔丁基)类似物与先前研究的3-或3-和4-取代的2-噻吩基(二叔丁基)甲醇进行了比较。的平衡常数为顺-反rotamerization([顺] / [反])比对于较小的二-稍大叔丁基衍生物。在分子内氢键合的抗旋转异构体中,1 H NMR位移都没有。羟基 质子 也不是OH拉伸频率 指标分子内氢键强度的变化很大程度上受叔烷基基团变化的影响;因此,平衡常数的这些变化必须归因于空间效应的变化。具有较大叔烷基基团的化合物的旋转壁垒得到大大增强和更好的区分。在所有三组中,syn → anti和anti → syn旋转势垒是线性相关的,任何一个都可以与自由能差相关。但是,数据不符合经典的Leffler-Grunwald型速率-平衡关系的标准。分子力学计算(MMFF94力场)很好地说明了二-1-金刚烷基,(1-金刚烷基)(叔丁基)和二叔丁基衍生物的旋转异构体对的自由能差
