N-杂环卡宾L与BeCl2定量反应生成L：BeCl2 1(L：=：C{N(2，6-(Pr2C6H3)-C-I)CH}(2))。1与LiBH4反应合成了卡宾稳定的铍硼氢化物单体L：Be(BH4)(2)2。化合物3由2与Na-2[Fe(CO)(4)]中心点状二氧六环反应得到，代表咪唑环的一种不寻常的“双重还原”(即C=C主链的硼氢化和C2卡宾中心的氢化)。
The reaction of N-heterocyclic carbene, L:, with BeCl2 quantitatively yields L:BeCl2 1 (L: = :C{N(2,6-(Pr2C6H3)-C-i)CH}(2)). The carbene-stabilized beryllium borohydride monomer L:Be(BH4)(2) 2 is prepared by the reaction of 1 with LiBH4. Compound 3, prepared by the reaction of 2 with Na-2[Fe(CO)(4)]center dot dioxane, represents an unusual "dual reduction" of the imidazole ring (i.e., hydroboration of the C=C backbone and hydrogenation of the C2 carbene center).
