单体双配位卡宾络合物 (IPr)CuO-t-Bu (1)（IPr = 1,3-双（2,6-二异丙基苯基）咪唑-2-亚基）很容易与三乙氧基硅烷等硅烷反应，形成铜-铜距离非常短的二聚氢化铜 (I) 络合物 (2)。 2 3-己炔氢化得到单体铜(I)乙烯基络合物。
The monomeric, two-coordinate carbene complex (IPr)CuO-t-Bu (1) (IPr = 1,3-bis(2,6-diisopropylphenyl )imidazol-2-ylidene) reacts readily with silanes such as triethoxysilane, forming a dimeric copper(I) hydride complex (2) with a very short copper-copper distance. Hydrocupration of 3-hexyne by 2 affords a monomeric copper(I) vinyl complex.
