This work discloses that a simple change in the anion of a copper(II) reagent along with the reaction solvent can dramatically alter the course of a Cp*RhIII‐catalyzed C−H activation–annulation reaction leading to completely switchable chemoselective products. The nature of the anion in terms of its coordinating ability and basicity, and also the polarity of the solvent have been found to be the crucial
这项工作表明,
铜(II)试剂的阴离子与反应溶剂的简单变化会显着改变Cp * Rh III催化的CH-H活化-环化反应的过程,从而导致完全可切换的
化学选择性产物。就其配位能力和碱性而言,阴离子的性质以及溶剂的极性已被发现是观察到的发散的关键因素。
