1,12-Closo-C_2B_(10)H_(12)或其C,C-二甲基类似物在液氨中用钠还原,然后用{CpCo}~(2+)、{(芳烃)Ru}~(2+)或{(dppe)Ni}~(2+)片段进行重氮化,得到4,1,10-MC_2B_(10)物种的第一个实例;这些化合物的合成得到合适的4,1,12-MC 2B 10异构体,通过已知4,1,6-MC 2B 10化合物。
Reduction of 1,12-closo-C2B10H12 or its C,C-dimethyl analogue with sodium in liquid ammonia followed by metallation with {CpCo}2+, {(arene)Ru}2+ or {(dppe)Ni}2+ fragments affords the first examples of 4,1,10-MC2B10 species; thermolysis of these yields the appropriate 4,1,12-MC2B10 isomers, unavailable for (arene)Ru metallacarboranes by similar thermolysis of known 4,1,6-MC2B10 compounds.
