  Convenient Formation of Diphenylmethyl Esters Using Diphenylmethyl Trichloroacetimidate

  摘要：

  Diphenylmethyl trichloroacetimidate is a useful reagent for the protection of carboxylic acids as their corresponding diphenylmethyl esters. These esterifications proceed rapidly without the need for an added catalyst or promoter. A variety of carboxylic acid substrates undergo esterification in excellent yields with the trichloroacetimidate reagent, including substrates possessing acid- or base-sensitive functionality. Protection of a carboxylic acid with a highly enolizable alpha-stereocenter using diphenylmethyl imidate was also accomplished without racemization.

  now discussed are rate coefficients for the reactions of benzoic acid and 32 ortho-substituted benzoic acids with diazodiphenylmethane (DDM) at 30.0 °C in 11 alcohols including 2-methoxyethanol. The reaction involves a rate-determining proton transfer. The results have been subjected to correlation analysis in two ways. (a) For the reactions of a given acid in the various alcohols, the log k values are

  现在讨论的主要结果是苯甲酸和32种邻位苯甲酸与重氮二苯甲烷（DDM）在30.0°C下在11种醇（包括2-甲氧基乙醇）中反应的速率系数。该反应涉及确定速率的质子转移。对结果进行了两种相关性分析。（a）对于给定酸在各种醇中的反应，通过在适当的溶剂参数上进行多元回归将log k值关联起来。（b）对于给定酒精中的反应，对数k通过使用包含感应，共振和空间参数的扩展Hammett方程的适当形式，可以将各种酸的相关值关联起来。与早期工作中一样，类型（a）的分析涉及醇ROH中基团R的σ*值，介电常数Kirkwood函数，f（μ）=（μ-1）/（2μ+ 1）和ñ γ ħ，在氢原子数γ在醇-位。这些相关性产生了有关邻位取代基对特定和非特定溶剂作用的相对重要性的影响的信息。在类型分析中（b）的相关性方程建立了有限的一组取代基（最多至18），其特征参数σ我，σ [R ，和v（由Charton确定）被很好地建立，并

  An esterification and amination of benzylic C–H bonds was developed by using 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) under metal- and iodide-free conditions. Both carboxylic acids and amines could be used as ideal coupling partners for the oxidative coupling reactions with various diarylmethanes. A close to equal amount of coupling reagents was enough to afford the product in good to high yields

  在不含金属和碘化物的条件下，使用 2,3-二氯-5,6-二氰基-1,4-苯醌 (DDQ) 开发了苄基 C-H 键的酯化和胺化。羧酸和胺均可用作与各种二芳基甲烷进行氧化偶联反应的理想偶联伙伴。接近等量的偶联试剂足以以良好至高产率提供产物。
