a one-step process. These complexes were used as pre-catalysts in the Buchwald–Hartwig amination of cyclic secondary amines with aryl chlorides. A range of cyclic secondary amines were tolerated to a wide variety of aryl chlorides in presence of 1 mol% catalyst loading under mild conditions. Under the tested reaction conditions, the expected N-arylamines were obtained in moderate to high yields. The
摘要 一步法成功制备了六种带有不同辅助
配体(如
吡啶、1-甲基
咪唑、
4,5-二甲基噻唑和
3-溴喹啉)的新型
钯N-杂环卡宾配合物。这些配合物在环状仲胺与芳基
氯的 Buchwald-Hartwig 胺化反应中用作预催化剂。在温和条件下,在 1 mol% 催化剂负载量存在下,一系列环状仲胺对多种芳基
氯具有耐受性。在测试的反应条件下,以中等到高产率获得了预期的N-芳基胺。结果表明,这些新型
钯配合物是 Buchwald-Hartwig 胺化反应的有效催化剂。 图文摘要
