• Friedel-Crafts Alkylation with Carbenium Ions Generated by Electrochemical Oxidation of Stannylmethyl Ethers

  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.

  Phosphomolybdic acid (H3PMo12O40) was found to be a bifunctional catalyst for C─C bond formation via the dehydrative reaction of diarylmethanols with various nucleophiles, including 2‐naphthols, indoles, benzofuran and benzothiophene. The protons in the catalyst might play a critical role in the activation of alcohol, while the polyanion was advantageous for stabilizing the carbocation species. The

  磷钼酸（H 3 PMo 12 O 40）是通过二芳基甲醇与各种亲核试剂，包括2-萘酚，吲哚，苯并呋喃和苯并噻吩的脱水反应，形成C-C键的双功能催化剂。催化剂中的质子可能在醇的活化中起关键作用，而聚阴离子有利于稳定碳正离子。协同催化体系显示出其自身的优点，例如高反应速率，低催化剂负载，温和的条件，极好的收率（高达99％）和良好的官能团相容性。

  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

  A general and practical method to synthesize 2-substituted benzofurans and indoles is described. This method employs easily accessible N-tosylhydrazones and o-hydroxy or o-amino phenylacetylenes as substrates. The reaction proceeds through a CuBr-catalyzed coupling–allenylation–cyclization sequence under ligand-free conditions.
