  Friedel–Crafts alkylation of electron rich arenes can be achieved by stabilized carbenium ions which are generated by single cell anodic oxidation of stannylmethyl ethers at low potential. The use of NaHCO3 as an additive ensures close‐to‐neutral conditions enabling the reaction with arenes bearing acid‐sensitive groups such as O‐TBS, O‐Tr, O‐MOM, O‐THP.

  compatible with systems for diarylmethyl ester coupling. Furthermore, the reaction can be performed stereospecifically to generate stereoinverted products. On the basis of DFT calculations, it is proposed that the oxidative addition of the diarylmethyl 2,3,4,5,6-pentafluorobenzoate substrate occurs via an SN2 pathway, which results in the inverted products. Mechanistic studies indicate that oxidative addition

  描述了通过 Pd 催化的 2,3,4,5,6-五氟苯甲酸二芳基甲酯和芳基硼酸之间的 Suzuki-Miyaura 反应合成三芳基甲烷。该系统在温和的条件下运行，具有广泛的底物范围，包括不包含扩展芳族取代基的二苯甲醇衍生物的偶联。这一点很重要，因为这些底物会导致药物中普遍存在的三芳基甲烷产物类型，而这些底物以前并不与二芳基甲酯偶联系统兼容。此外，该反应可以立体特异性地进行以产生立体反转产物。在 DFT 计算的基础上，提出 2,3,4,5,6-五氟苯甲酸二芳基甲酯底物的氧化加成是通过 S N2 通路，从而产生倒置产物。机理研究表明，将 2,3,4,5,6-五氟苯甲酸二芳基甲酯底物氧化加成到 (IPr)Pd(0) 会导致 O-C(苄基) 键的选择性断裂，部分原因是稳定的 η苄基配体与 Pd 之间的3 -相互作用。这与先前描述的涉及苯基酯的 Pd 催化的 Suzuki-Miyaura 反应形成对比，后者涉及
• Copper-mediated arylation with arylboronic acids: Facile and modular synthesis of triarylmethanes

  A facile and modular synthesis of triarylmethanes was achieved in good yield via a two-step sequence in which the final step is the copper(II)-catalyzed arylation of diarylmethanols with arylboronic acids. By using this protocol a variety of symmetrical and unsymmetrical triarylmethanes were synthesized. As an application of the newly developed methodology, we demonstrate a high-yielding synthesis of the triarylmethane intermediate towards an anti-breast-cancer drug candidate.

  We present a PdCl2-catalyzed protocol for highly efficient allylation and benzylation of a rich variety of N-, O-, and S-containing heteroarenes under base/acid, additive, and ligand-free conditions. The method represents the very few examples for simple, universally applicable, clean, and atom-efficient functionalization of heteroarenes.

  An efficient palladium-catalyzed Suzuki coupling of 1,1-diarylmethyl-trimethylammonium triflates with arylboronic acids is reported. This reaction offers a novel approach to triarylmethane derivatives in good to excellent yields with the palladium-catalyzed C–N bond cleavage as the key feature. Broad substrate scope regarding both reaction partners are observed. Moreover, reactive functional groups
