  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。

The reaction is tolerant to a wide variety of functional groups including other reactive olefins. Unlike the more reactive Ir catalysts, monosubstituted alkenes give almost exclusively the 2-alkenes.

  and mild method for the coupling of aryl iodides and aliphatic alcohols that does not require the use of alkoxide bases is described. The reactions can be performed in neat alcohol. For more precious alcohols, the etherification was carried out in toluene as solvent using 2 equiv of alcohol. Additionally, the cross-coupling of an optically active benzylic alcohol with an unactivated aryl halide was demonstrated
