and palladium(II) was analyzed by ESI mass spectrometry. X-ray structures were determined for palladium(II) complex with 1,2-bis(pyrazol-1-yl)benzene and copper(II) complex with 1,4-difluoro-2,3-bis(pyrazol-1-yl)benzene, revealing an unusual seven-membered chelate cycle formation.
通过在1,2-二氟,1,2,3,4-四氟,1,2 ,4,5-四氟和六氟苯。观察到的取代模式表明了早期TS的形成,从而使得氟被邻位亲核攻击位点激活。通过ESI质谱分析合成的配体与铜(II)和钯(II)的络合。确定了具有1,2-双(吡唑-1-基)苯的钯(II)配合物和具有1,4-二氟-2,3-双(吡唑-1-基)的铜(II)配合物的X射线结构)苯,揭示了一个不寻常的七元螯合物循环形成。
