Ag2O in CH2Cl2 to form carbene complexes, [DPCP-(NHC:Bu-tAgCl)2] and [DPCP-(NHC:DippAgCl)2], no pure products are found in case of Me substituted salt. Under similar conditions, Cu2O with the N-Dipp substituted imidazolium salt gives [(DPCP-(ImidDipp)2Cl][CuICl2], a [CuICl2]− complex with the imidazolium ion as counter cation. However, a carbaphosphazene-anchored NHC complex of Cu, [DPCP-(NHC:DippCuCl)2]
通过用N-Me,N-叔-Bu和N-Dipp咪唑(Dipp = 2,6-二异丙基苯基)处理式(ClCN)2(Ph 2 PN)的六元二氯二苯基二咔唑磷腈来合成咔唑固定的咪唑鎓盐在甲苯中。虽然浸渍和叔-Bu substituiertem咪唑鎓盐经历有Ag的简便反应2在2 CH 2 O 2氯2以形成卡宾配合物,[DPCP-(NHC:卜吨AgCl电极)2 ]和[DPCP-(NHC:浸AgCl电极)2 ],在Me取代盐的情况下,没有发现纯净的产品。在相似的条件下,具有N-Dipp取代的咪唑鎓盐的Cu 2 O得到[(DPCP-(Imid Dipp)2 Cl] [Cu I Cl 2 ]- [Cu I Cl 2 ] -配合物,咪唑鎓离子作为抗衡阳离子。但是,也可以通过在60°C下于乙腈中加热Cu 2 O和N-Dipp咪唑鎓盐的混合物来合成铜的碳磷腈固定的NHC络合物[DPCP-(NHC:Dipp CuCl)2
