Abstract

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.

摘要

在液氨中用钠还原1,12-闭式-C₂B₁₀H₁₂或其C,C-二甲基类似物，然后用{CpCo}²⁺、{(芳烃)Ru}²⁺或{(dppe)Ni}²⁺片段进行金属化反应，得到了首例4,1,10-MC₂B₁₀物种；对这些物种进行热解得到了相应的4,1,12-MC₂B₁₀异构体，而通过对已知的4,1,6-MC₂B₁₀化合物进行类似热解，无法得到(芳烃)Ru金属碳硼烷的这些异构体。
