• Copper-Catalyzed Protodecarboxylation of Aromatic Carboxylic Acids
  作者：Lukas J. Gooßen、Werner R. Thiel、Nuria Rodríguez、Christophe Linder、Bettina Melzer

  DOI：10.1002/adsc.200700223

  日期：2007.10.8

  A catalyst generated from copper(I) oxide and 4,7-diphenyl-1,10-phenanthroline for the first time allows the catalytic protodecarboxylation even of deactivated aromatic carboxylic acids, giving rise to the corresponding arenes. Based on DFT calculations, a reaction pathway is proposed that accurately reflects the experimental results, such as the observed reactivity order of the substrates.

  首次由氧化铜（I）和4,7-二苯基-1,10-菲咯啉生成的催化剂甚至可以使失活的芳族羧酸进行催化原脱羧，从而生成相应的芳烃。基于DFT计算，提出了一种反应路径，可以准确反映实验结果，例如观察到的底物反应顺序。

  The invention relates to a method for decarboxylating C—C bond formation by reacting carboxylic salts with carbon electrophiles in the presence of transition metal compounds as catalysts. The method represents a decarboxylating C—C bond formation of carboxylic acid salts with carbon electrophiles, wherein the catalyst contains two transition metals and/or transition metal compounds, from which one is present, preferably, in the oxidation step, which are different from each other by one unit, and catalyzes a radical decarboxylation which is absorbed during the second oxidation steps, which are different from each other by two units and catalyzes the two electron processes of a C—C bond formation reaction.

  该发明涉及一种方法，通过在过渡金属化合物存在的情况下，将羧酸盐与碳亲电体反应以脱羧基C—C键形成。该方法代表了一种羧酸盐与碳亲电体的脱羧基C—C键形成，其中催化剂包含两种过渡金属和/或过渡金属化合物，其中一种存在于氧化步骤中，这两种过渡金属或化合物相互之间相差一个单位，并催化在第二氧化步骤中吸收的自由基脱羧反应，这两种过渡金属或化合物相互之间相差两个单位，并催化C—C键形成反应的双电子过程。

  A protocol for the synthesis of hindered 4-aryl 2-aminopyrimidines from β–keto esters is described. The process employs trifluoroethanol as an essential additive to promote the guanidine condensation reaction, enabling the synthesis of 25 aryl- and heteroaryl substituted aminopyrimidines in good yields and high purities with no column chromatography. The conditions described herein are readily scalable
