  Friedel−Crafts Arylation Reactions of N-Sulfonyl Aldimines or Sulfonamidesulfones with Electron-Rich Arenes Catalyzed by FeCl₃·6H₂O: Synthesis of Triarylmethanes and Bis-heteroarylarylmethanes

  摘要：

  The FeCl3 center dot 6H(2)O-catalyzed Friedel-Crafts arylation reactions of N-sulfonyl aldimines or sulfonamidesulfones with electron-rich arenes and heteroarenes, which lead to the formation of triarylmethanes and bis-heteroarylarylmethanes, are developed. The use of mild reaction conditions, low catalytic loading, high yield, and single step synthesis are the advantages of the present procedure.

  including Brönsted acid ionic liquids (BAILs) and traditional ionic liquids were designed and synthesized. BAILs catalyzed Friedel–Crafts (F–C) alkylation was applied in this specific reaction for the first time. And the BAILs showed bifunctional properties acting as catalyst and solvent. Research shows that BAILs can be used for catalyzing F–C alkylations of electron-rich arenes with aromatic or aliphatic

  三芳基甲烷（TRAM）和二芳基烷烃（DIAA）是有价值的中间体，在许多领域都有广泛的应用。通常从活化的芳基醛的酸催化的双芳基化获得TRAM。然而，该合成带来许多问题，例如苛​​刻的反应条件以及过量溶剂和/或有毒金属废物的处置。在这项研究中，设计并合成了一些功能化的离子液体，包括布朗斯台德酸性离子液体（BAIL）和传统离子液体。BAIL催化的Friedel-Crafts（FC）烷基化首次在该特定反应中应用。并且BAIL显示出充当催化剂和溶剂的双功能性质。研究表明，BAILs可在温和的反应条件下成功地用芳族或脂族醛催化富电子芳烃的F-C烷基化。此外，含有三氟甲基磺酸根阴离子的BAIL具有比其他BAIL和传统离子液体更高的活性。[HSO3- pmim] [OTf]在40°C下存在20 mol％的BAIL时得到最高的收率，从而得到相应的TRAMs衍生物。经过五个周期后，产率保持在93–97％左右。

  Cationic ruthenium porphyrin complex was found to be an efficient catalyst for the Friedel-Crafts type reaction of arenes with imines. The use of a structurally rigid tetradentate porphyrin as the equatorial ligand and weakly coordinating axial ligand is the key to bring out the catalytic reactivity of ruthenium for the reaction.
