Out‐of‐plane steric bulk furnished by a cyclophane substituent on iodine(III) strongly destabilizes the transition state in the reductive elimination from diaryliodonium salts and leads to regiochemical control (dubbed SECURE), as is demonstrated by computational and experimental studies. This approach should be general for high‐valent main‐group and transition metal ions. X=N3, OAc, PhO, CF3CH2O,
正如计算和实验研究所证明的那样,碘(III)上的环芳取代基提供的面外空间体积强烈地破坏了二芳基碘鎓盐还原消除过程中的过渡态的稳定性,并导致区域化学控制(称为“安全”)。这种方法对于高价主族和过渡金属离子应该是通用的。 X=N 3 、OAc、PhO、CF 3 CH 2 O、SCN、PhS。
