Deprotonation of [IPr]I (1) with Co{N(SiMe)} readily affords the abnormal N-heterocyclic carbene (aNHC) complex (aIPr)CoI (2) (aIPr = 1,3-bis(2,6-iPrCH)-2-phenyl-imidazol-4-ylidene). Treatment of 1 with NaHBEt yields (aIPr)BEt (3) that serves as an aNHC-transfer agent and yields (aIPr)Co{N(SiMe)} (4) on reaction with Co{N(SiMe)}.
[IPr]I (1) 与Co{N(SiMe)}发生去质子化反应，很容易得到异常的N-杂环卡宾（aNHC）配合物 (aIPr)CoI (2)（aIPr = 1,3-双(2,6-异丙基苯基)-2-苯基-咪唑-4-亚基）。用NaHBEt处理1得到 (aIPr)BEt (3)，它作为一种aNHC转移剂，与Co{N(SiMe)}反应生成 (aIPr)Co{N(SiMe)} (4)。
