  corresponding triflates, are subject to nucleophile-triggered fragmentation as part of a tandem process for generating functionalized alkynes. Advantages to the use of nonaflates in lieu of triflates include cost and stability. Computational analysis supports a postulated fragmentation mechanism involving a closed (cyclic) transition state with concerted extrusion of lithium sulfonate. Vinylogous acyl nonaflates

  摘要 像相应的三氟甲磺酸酯一样，乙烯基类壬二酸酯也经历了亲核试剂引发的断裂，这是串联反应过程的一部分，用于生成功能化炔烃。使用壬酸乙酯代替三氟甲磺酸盐的优点包括成本和稳定性。计算分析支持一种假定的碎裂机制，该碎裂机制涉及闭合（环状）过渡态以及磺酸锂的协同挤出。 像相应的三氟甲磺酸酯一样，乙烯基类壬二酸酯也经历了亲核试剂引发的断裂，这是串联反应过程的一部分，用于生成功能化炔烃。使用壬酸乙酯代替三氟甲磺酸盐的优点包括成本和稳定性。计算分析支持一种假定的碎裂机制，该碎裂机制涉及闭合（环状）过渡态以及磺酸锂的协同挤出。
