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。
