parameters of stabilized sulfur ylides, methylsulfonyl‐, and methylsulfinyl stabilized carbanions have been determined from the rates of their reactions with benzhydrylium ions and quinone methides. Direct comparisons of the nucleophilic reactivities of sulfur and phosphorus ylides as well as their related carbanions have now become possible.
稳定化的硫烷基化物,甲基磺酰基和甲基亚磺酰基化的碳负离子的亲核参数已根据它们与苯甲酰鎓离子和醌甲基化物的反应速率确定。现在可以直接比较硫和磷的磷化物及其相关碳负离子的亲核反应性。
