    摘要:
    2-硫代双环桥头化合物相对于母体化合物的溶剂分解速率比随环系统的柔性而增加,这支持了作者评估π缀合随骨架柔韧性增强的方法的适当性。基于尚未通过这种方法检测到由于羰基共轭引起的明显的稳定这一事实,叔α-羰基阳离子中的羰基π共轭(如果存在)太小而无法通过实验检测。

    Solvolysis of 2-Thioxo Bicyclic Bridgehead Derivatives:  Evaluation of π-Conjugative Stabilization of α-Thiocarbonyl Carbocations
    摘要:
    The ethanolysis rates of 3,3-dimethyl-2-thioxobicyclo[2.2.2]oct-1 triflate and 3,3-dimethyl-2-thioxobicyclo[3.2.2]non-1-yl triflate relative to their corresponding parent compounds (3,3-dimethylbicyclo[2.2.2]oct-1-yl triflate and 3,3-dimethylbicyclo[3.2.2]non-1-yl triflate, respectively) at 25.0 degrees C increase from 10(-6.2) to 10(-2.5). The increase in the rate ratios with the flexibility of the ring system supports the applicability of the authors' methodology to change the conjugative ability of bridgehead carbocations. Formation of 3,3-dimethyl-1,2-epithio-2-ethoxybicyclo[3.2.2]nonane in the ethanolysis of 3,3-dimethyl-2-thioxobicyclo[3.2.2]non-1-yl 2,2,2-trifluoroethanesulfonate indicates cyclization of the intermediate 3,3-dimethyl-2-thioxobicyclo[3.2.2]nonyl cation into an episulfide cation. Computational studies at the HF/6-31G* level indicate that the resonance interaction between the cationic center and the C=S pi system is greater in the 3,3-dimethyl-2-thioxobicyclo[3.2,2]nonyl cation than in the 3,3-dimethyl-2-thioxobicyclo[2.2.2]octyl cation.
