thermal transylidation to bromo- and iodobenzenes. The reaction probably involves initial thermal generation of bissulfonylcarbene (Tf2C:), followed by nucleophilic attack of a halobenzene toward the electron-deficient carbene center. Solid-state structures of these aliphatic phenylhalonium ylides were analyzed and compared with each other. © 2011 Wiley Periodicals, Inc. Heteroatom Chem 22:325–330, 2011;
合成了具有双(三氟甲基磺酰基)-亚甲基基团的脂肪族苯基氯鎓叶立德。4-(三氟甲基)苯基溴鎓双(三氟甲基磺酰基)甲基化物在作为溶剂的氯苯中在130°C下的热转移,以中等产率得到苯基氯化鎓双(三氟甲基磺酰基)甲基化物。苯基溴鎓和苯基碘鎓叶立德也可以通过热转移基化为溴苯和碘苯来制备。该反应可能涉及双磺酰基卡宾 (Tf2C:) 的初始热生成,然后是卤代苯对缺电子卡宾中心的亲核攻击。对这些脂肪族苯基卤鎓叶立德的固态结构进行了分析和相互比较。© 2011 Wiley Periodicals, Inc. 杂原子化学 22:325–330, 2011; 在 wileyonlinelibrary.com 上在线查看这篇文章。DOI 10.
