  The present invention relates to copper-catalyzed carbon-heteroatom and carbon-carbon bond-forming methods. In certain embodiments, the present invention relates to copper-catalyzed methods of forming a carbon-nitrogen bond between the nitrogen atom of an amide or amine moiety and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. In additional embodiments, the present invention relates to copper-catalyzed methods of forming a carbon-nitrogen bond between a nitrogen atom of an acyl hydrazine and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. In other embodiments, the present invention relates to copper-catalyzed methods of forming a carbon-nitrogen bond between the nitrogen atom of a nitrogen-containing heteroaromatic, e.g., indole, pyrazole, and indazole, and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. In certain embodiments, the present invention relates to copper-catalyzed methods of forming a carbon-oxygen bond between the oxygen atom of an alcohol and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. The present invention also relates to copper-catalyzed methods of forming a carbon-carbon bond between a reactant comprising a nucleophilic carbon atom, e.g., an enolate or malonate anion, and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. Importantly, all the methods of the present invention are relatively inexpensive to practice due to the low cost of the copper comprised by the catalysts.

  本发明涉及铜催化的碳-杂原子和碳-碳键形成方法。在某些实施例中，本发明涉及铜催化的方法，用于在酰胺或胺基团的氮原子与芳基、杂原基或乙烯卤代物或磺酸酯的活化碳之间形成碳-氮键。在其他实施例中，本发明涉及铜催化的方法，用于在酰基肼的氮原子与芳基、杂原基或乙烯卤代物或磺酸酯的活化碳之间形成碳-氮键。在另一些实施例中，本发明涉及铜催化的方法，用于在含氮杂环芳烃（例如吲哚、吡唑和吲哌）的氮原子与芳基、杂原基或乙烯卤代物或磺酸酯的活化碳之间形成碳-氮键。在某些实施例中，本发明涉及铜催化的方法，用于在醇的氧原子与芳基、杂原基或乙烯卤代物或磺酸酯的活化碳之间形成碳-氧键。本发明还涉及铜催化的方法，用于在包含亲核碳原子的反应物（例如烯醇酸盐或丙二酸盐负离子）与芳基、杂原基或乙烯卤代物或磺酸酯的活化碳之间形成碳-碳键。重要的是，由于催化剂中铜的低成本，本发明的所有方法都相对廉价。

  undivided cell, of Ph3P in the presence of a carboxylic acid in CH2Cl2 containing 2,6-lutidinium perchlorate as the supporting electrolyte was shown to generate the corresponding acyloxyphosphonium ion, Ph3P+-OCOR, which was converted in situ to esters, amides, and β-lactams under mild conditions.

  结果表明，在羧酸存在下的CH 2 Cl 2中，含高氯酸2,6-lut啶鎓作为辅助电解质的PH 3 P在不分隔的电池中恒流电解会生成相应的酰氧基phosph离子Ph 3 P + -OCOR，在温和条件下原位转化为酯，酰胺和β-内酰胺。
