A catalyst composition for a cross-coupling reaction comprising a nickel metal source, a fluorine source, and a nitrogen-containing heterocyclic compound having a specific structure, or a phosphine compound. Using this catalyst composition, a cross-coupled compound R5-R6 (wherein R5 and R6 are an aryl or heteroaryl group, or a linear, branched or cyclic alkyl group or a linear, branched or cyclic alkenyl group) is produced with a high selectivity by allowing an organometallic compound of the formula (2) R5-MY1 or the formula (3) R5-M-R5 (wherein R5 is the same as defined above, M is a Mg or Zn atom, and Y1 is a halogen atom) to react with a compound of the formula (4) R6-Y2 (wherein R6 is the same as defined above, and Y2 is a halogen atom, a methanesulfonate group, a toluenesulfonate group or a trifluoromethanesulfonate group).
一种用于交叉偶联反应的催化剂组合物,由镍金属源、氟源和具有特定结构的含氮杂环化合物或膦化合物组成。使用这种催化剂组合物,通过使式(2)R5-MY1 或式(3)R5-M-R5(其中 R5 与上文所定义的相同)的有机金属化合物以高选择性生成交叉偶联化合物 R5-R6(其中 R5 和 R6 为芳基或杂芳基,或直链、支链或环状烷基,或直链、支链或环状烯基)、M为镁原子或锌原子,Y1为卤素原子)与式(4)R6-Y2(其中 R6 与上述定义相同,Y2 为卤素原子、甲磺酸基团、甲苯磺酸基团或三氟甲磺酸基团)化合物反应。
