The preparation of a 1,3-bis(2,6-terphenyl)imidazolium salt and the first coordination complex containing a 1,3-bis(2,6-terphenyl)imidazol-2-ylidene NHC (IDitop) is reported; comparison of the steric parameters of IDitop with commonly used bulky NHCs such as 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene (IDip) indicates a significantly greater cone angle for the former, and the molecular structures of [AgCl(IDitop)], the parent diazabutadiene of IDitop and the 1,3-bis(2-phenylphenyl)imidazol-2-ylidene (IBp) complex [AgCl(IBp)] are reported.
报道了 1,3-双(2,6-三联苯)咪唑鎓盐和第一个含有 1,3-双(2,6-三联苯)咪唑-2-亚基 NHC (IDitop) 的配位络合物的制备;将 IDitop 与常用的大体积 NHC(例如 1,3-双(2,6-二异丙基苯基)咪唑-2-亚基(IDip))的空间参数进行比较,表明前者的锥角明显更大,并且 [报道了 IDitop 的母体二氮杂丁二烯 AgCl(IDitop)] 和 1,3-双(2-苯基苯基)咪唑-2-亚基 (IBp) 络合物 [AgCl(IBp)]。
