Abstract

The nature of nucleophiles greatly influences the reactivity patterns of 13-vertex carboranes. μ-1,2-(CH(2))(3)-1,2-C(2)B(11)H(11) reacts with Et(3)N/MeOH, pyridine or bipyridine to give cage-boron and -carbon extrusion products nido-CB(10) or closo-CB(10), or a cage-boron extrusion compound closo-C(2)B(10) while the cage-carbon extrusion species closo-CB(11) monoanions are produced by treatment with MeOH or Ph(3)P.

摘要

亲核试剂的性质极大地影响了 13 顶点碳硼烷的反应模式。μ-1,2-(CH(2))(3)-1,2-C(2)B(11)H(11)与 Et(3)N/MeOH、吡啶或联吡啶反应，生成笼硼和笼碳挤出产物 nido-CB(10)或 closo-CB(10)，或笼硼挤出化合物 closo-C(2)B(10)，而用 MeOH 或 Ph(3)P 处理则生成笼碳挤出物种 closo-CB(11)单阴离子。
