title: Selective cage boron/carbon extrusion reaction of 13-vertex carborane μ-1,2-(CH2)3-1,2-C2B11H11: formation of nido-CB10, closo-CB10, and closo-C2B10 species.
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.
