The present invention relates to a process for the formation of carbon-carbon bonds starting from a copper compound of an aryl, heteroaryl, alkene or alkine and an aryl, heteroaryl, alkene or alkine compound having a suitable leaving group. The copper compounds can be prepared inter alia by means of transmetalliziation from a Grignard or lithium compound. Cross-coupling of these compounds with e.g. a halogen-substituted aryl compound is carried out by means of an iron or cobalt catalyst using suitable solvents and suitable additives.
本发明涉及一种从芳基、杂环烷基、烯烃或
炔烃的
铜化合物和具有适当离去基团的芳基、杂环烷基、烯烃或
炔烃化合物开始形成碳-碳键的过程。这些
铜化合物可以通过从
格氏试剂或
锂化合物的转
金属化方法制备。这些化合物与例如卤代芳基化合物的交叉偶联是通过使用适当溶剂和适当添加剂的
铁或
钴催化剂来实现的。
