and -CF(3) groups are compatible. The method also allows for consecutive cross-coupling processes in one pot, as exemplified by the efficient preparation of compound 12, and has been applied to the first synthesis of the cytotoxic marine natural product montipyridine 8. In contrast to the clean reaction of (hetero)aryl chlorides, the corresponding bromides and iodides are prone to a reduction of their
简单的铁盐,如 FeCl(n)、Fe(acac)(n) (n = 2,3) 或 salen 络合物 4 被证明是高效、廉价、毒理学无害且环境友好的预催化剂,可用于许多交叉- 烷基或芳基格氏试剂、锌酸盐或有机锰物质与芳基和杂芳基氯化物、三氟甲磺酸盐甚至甲苯磺酸盐的偶联反应。原位制备的正式成分 [Fe(MgX)(2)] 的“无机格氏试剂”可能构成负责催化周转的传播物种,在许多情况下,即使在室温或室温以下,这种转化率也以前所未有的速度发生。由于反应条件异常温和,一系列官能团如酯、醚、腈、磺酸盐、磺酰胺、硫醚、缩醛、炔烃和 -CF(3) 基团是相容的。
