One aspect of 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-sulfur bond between the sulfur atom of a thiol moiety and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. In other embodiments, the present invention relates to copper(II)-catalyzed methods of forming a carbon-nitrogen bond between the nitrogen atom of an amide 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-carbon bond between the carbon atom of cyanide ion and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. In another embodiment, the present invention relates to a copper-catalyzed method of transforming an aryl, heteroaryl, or vinyl chloride or bromide into the corresponding aryl, heteroaryl, or vinyl iodide. Yet another embodiment of the present invention relates to a tandem method, which may be practiced in a single reaction vessel, wherein the first step of the method involves the copper-catalyzed formation of an aryl, heteroaryl, or vinyl iodide from the corresponding aryl, heteroaryl, or vinyl chloride or bromide; and the second step of the method involves the copper-catalyzed formation of an aryl, heteroaryl, or vinyl nitrile, amide or sulfide from the aryl, heteroaryl, or vinyl iodide formed in the first step.
本发明的一个方面涉及铜催化的碳-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,用于在芳基、杂芳基或乙烯卤代物或磺酸盐的活性碳和巯基官能团的硫原子之间形成碳-硫键。在其他实施例中,本发明涉及铜(II)催化的方法,用于在芳基、杂芳基或乙烯卤代物或磺酸盐的活性碳和酰胺的氮原子之间形成碳-氮键。在某些实施例中,本发明涉及铜催化的方法,用于在氰离子的碳原子和芳基、杂芳基或乙烯卤代物或磺酸盐的活性碳之间形成碳-碳键。在另一实施例中,本发明涉及一种铜催化的方法,将芳基、杂芳基或乙烯氯化物或溴化物转化为相应的芳基、杂芳基或乙烯碘化物。本发明的另一实施例涉及串联方法,可以在单个反应容器中实施,其中该方法的第一步涉及从相应的芳基、杂芳基或乙烯氯化物或溴化物中铜催化形成芳基、杂芳基或乙烯碘化物;该方法的第二步涉及从第一步形成的芳基、杂芳基或乙烯碘化物中铜催化形成芳基、杂芳基或乙烯腈、酰胺或硫化物。
