  摘要：

  Benzylic alcohols and diarylmethanols with electron-donating substituents in the aromatic ring reacted with aliphatic alcohols in the presence of a catalytic amount of HCl to give the corresponding alkyl arylmethyl ethers. The reactivity of diarylmethanols in the intermolecular dehydration depended on the nature of substituents in the aromatic rings and structure of aliphatic alcohol.

• Iodine-catalyzed disproportionation of aryl-substituted ethers under solvent-free reaction conditions

  日期：——

  iodine produced triphenylmethane and the corresponding aldehydes and ketones. The electron-donating substituents facilitated the reaction, while the electron-withdrawing groups retarded it; the difference in reactivity is not very high. Such an observation may be in favour of hydride transfer, predominantly from the less electron rich side of the ether with more stable carbocation formation. With the isotopic

  碘被证明是在无溶剂反应条件下芳基取代的醚歧化的有效催化剂。将各种取代的1,1,1'，1'-四芳基二甲基醚转化为相应的二芳基酮和二芳基甲烷衍生物。由I 2催化的4-甲氧基苯基取代的醚的转化也产生了单烷基化和二烷基化的Friedel-Crafts产品。用催化量的碘处理三苯甲基烷基和三苯甲基苄基醚三苯甲烷以及相应的醛和酮。供电子的取代基促进了反应，而吸电子基团阻止了该反应。反应性差异不是很大。这种观察可能有利于氢化物转移，主要是从醚的电子富集较少的一侧开始，具有更稳定的碳正离子形成。通过同位素研究，可以确定，大部分的C–H键断裂在速率确定步骤中发生，而羰基氧原子则起源于起始醚，而不是空气。转化是在空气和氩气下进行的，HI不是起作用的催化剂。
• Chemoselective C-Benzylation of Unprotected Anilines with Benzyl Alcohols Using Re₂O₇ Catalyst
  作者：Rajender Nallagonda、Mohammad Rehan、Prasanta Ghorai

  DOI：10.1021/jo4028598

  日期：2014.4.4

  An unprecedented dehydrative C–C bond formation between unprotected anilines with benzyl alcohols is disclosed. Re2O7 catalyst (5 mol %) at elevated reaction temperature (80 °C) provided C-benzylanilines with high to excellent yields and with good chemoselectivities (over N-alkylation). A probable mechanism has been proposed based on mechanistic studies.
