  日期：——

  A mild one-pot protocol for the synthesis of symmetrical biaryls by sequential Ir-catalyzed C-H borylation and Cu-catalyzed homocoupling of arenes is described. The regiochemistry of the biaryl formed is sterically controlled as dictated by the C-H borylation step. The methodology is also successfully extended to heteroarenes. Some of the products obtained by this approach are impossible to obtain

  herein a supramolecular catalyst harnessing Zn⋅⋅⋅N interactions that binds to pyridine-like substrates as tight as it can be found in some enzymes. The distance and spatial geometry between the active site and the substrate binding site is ideal to target unprecedented meta-selective iridium-catalyzed C−H bond borylations with enzymatic Michaelis–Menten kinetics, besides unique substrate selectivity and

  使用底物和催化剂之间的二次相互作用是发现用于原子经济 C-H 键功能化的选择性过渡金属催化剂的有前途的策略。最强大的催化剂是通过反复试验筛选发现的，因为底物和催化剂之间的结合常数低，其中小的立体电子修饰会导致非常不同的反应性。为了规避这些限制并提高这些重要反应中反应性预测的水平，我们在此报告了一种利用 Zn⋅⋅⋅N 相互作用的超分子催化剂，该催化剂与类吡啶底物的结合与在某些酶中发现的一样紧密。
