The kinetics of the reactions between trimethyloxonium hexafluorophosphate and a series of tetra-n-butylammonium arenesulfonates have been studied in acetonitrile at −23.4°. With the oxonium salt concentration at about 0.01 M, two series of runs were carried out; Hammett plots of the second-order rate coefficients led to ϱ values of −1.18±0.04 for 0.04 M arenesulfonate salt and −1.07±0.02 for 0.16
六氟磷酸三甲基氧鎓与一系列芳烃磺酸四正丁基铵酯的反应动力学已经在乙腈中于-23.4°进行了研究。在氧盐浓度约为0.01 M的情况下,进行了两个系列的实验;二阶速率系数的Hammett图导致ϱ值对于0.04 M的芳族磺酸盐为-1.18±0.04,对于0.16 M的芳族磺酸盐为-1.07±0.02。还报道了三甲基氧鎓离子在乙腈中的溶剂分解动力学。
