to excellent yields. An efficient procedure is described for the oxidative homocoupling of functionalized Grignard reagents using a catalytic amount of dilithium tetrachlorocuprate(II) (CuLi2Cl4) in the presence of pure oxygen gas. This method is applied successfully to a variety of aryl, heteroaryl, alkyl, alkenyl and alkynyl halides, which are converted into the corresponding homocoupled products in
摘要 描述了一种在纯氧气存在下使用催化量的四氯铜酸二锂(II)(CuLi 2 Cl 4)对官能化格氏试剂进行氧化均偶联的有效程序。该方法已成功应用于各种芳基,杂芳基,烷基,烯基和炔基卤化物,这些卤化物以良好或极好的收率转化为相应的均偶联产物。 描述了一种在纯氧气存在下使用催化量的四氯铜酸二锂(II)(CuLi 2 Cl 4)对官能化格氏试剂进行氧化均偶联的有效程序。该方法已成功应用于各种芳基,杂芳基,烷基,烯基和炔基卤化物,这些卤化物以良好或极好的收率转化为相应的均偶联产物。
