Pyrolysis of bis(perfluoroalkanesulfonyl)bromonium ylides in various olefins results in highly stereospecific formation of cyclopropanes via unimolecular decomposition. Product analysis, kinetic study, substituent effects, and theoretical study revealed the generation of singlet bis(perfluoroalkanesulfonyl)carbenes stabilized by intramolecular coordination of sulfonyl oxygen.
双(全氟烷烃磺酰基)溴化铵在各种烯烃中的热解导致通过单分子分解的环丙烷的高度立体定向形成。产物分析,动力学研究,取代基作用和理论研究表明,通过磺酰基氧的分子内配位稳定了单线态双(全氟烷烃磺酰基)卡宾的生成。
