  thermo- and air-stable Pd0 complex from readily available electron-poor trifluoromethylated phosphine was serendipitously discovered. As detailed and comparative DFT calculations indicate, the stability of the complex is associated with unusually strong ligand–ligand noncovalent interactions. The unique stability and the presence of hydrophobic structural elements of the complex offer several practical

• Tuning Reactivity and Site Selectivity of Simple Arenes in C–H Activation: Ortho-Arylation of Anisoles via Arene–Metal π-Complexation

  Current approaches to achieve site selectivity in the C–H activation of arenes involve the use of directing groups or highly electron-poor arenes. In contrast, simple arenes, such as anisole, are characterized by poor reactivity and selectivity. We report that π-complexation to a Cr(CO)3 unit enhances the reactivity of anisoles providing an unprecedented ortho-selective arylation. This mild methodology

  目前在芳烃 C-H 活化中实现位点选择性的方法涉及使用导向基团或高度缺电子的芳烃。相比之下，简单的芳烃，例如苯甲醚，其特点是反应性和选择性差。我们报告说，与 Cr(CO)3 单元的 π 络合增强了苯甲醚的反应活性，从而提供了前所未有的邻位选择性芳基化。这种温和的方法可用于含有苯甲醚基序的生物活性化合物的后期功能化，从而可以通过很少的合成步骤构建新型有机支架。
