  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。

  日期：2003.8

  Aryl nitriles have been found to participate in cross-coupling and amination reactions via nickel-catalyzed activation of the C-CN bond. With the development of these synthetically useful transformations, aryl nitriles can now be considered along with aryl halides and sulfonates as viable substrates for these types of reactions.

  reactions. However, the substrates were mostly limited to reactive carbonyl compounds (aldehydes and ketones) or carbon‐carbon multiple bonds. Here, we describe the application of newly‐developed chelating bis(tzNHC)‐rhodium complexes (tz=1,2,3‐triazol‐5‐ylidene) for several reductive transformations. With these catalysts, the formal reductive methylation of amines using carbon dioxide, the hydrosilylation

  NHC-铑配合物（NHC = N-杂环卡宾）已被广泛用作氢化硅烷化反应的有效催化剂。但是，底物主要限于反应性羰基化合物（醛和酮）或碳-碳多重键。在这里，我们描述了新开发的螯合双（tz NHC）-铑配合物（tz = 1,2,3-三唑-5-亚烷基）在几种还原转化中的应用。使用这些催化剂，已经在温和的反应条件下实现了使用二氧化碳的胺的正式还原甲基化，酰胺和羧酸的氢化硅烷化以及使用羧酸的胺的还原烷基化。
