Bis[o-(hydrosilyl)phenyl]cuprates and bis[o-(fluorosilyl)phenyl]cuprates were prepared by reacting [o-(hydrosilyl)phenyl]lithiums and [o-(fluorosilyl)phenyl]lithiums, respectively, with copper salts, such as CuCN and Cu(OPiv)2. The phenylcuprates underwent oxidative coupling to afford 2,2′-bis(hydrosilyl)biphenyls and 2,2′-bis(fluorosilyl)biphenyls.
通过使[邻-(氢甲硅烷基)苯基]锂和[邻-(氟甲硅烷基)苯基]锂分别与铜盐反应制备双[邻-(氢甲硅烷基)苯基]癸酸酯和双[邻-(氟甲硅烷基)苯基]癸酸酯,例如CuCN和Cu(OPiv)2。对苯基铜酸酯进行氧化偶联,得到2,2'-双(氢甲硅烷基)联苯和2,2'-双(氟甲硅烷基)联苯。
