Perchlorocarborane and Perchloroneocarborane

Abstract

Direct chlorination of carborane and neocarborane results in undecachlorocarborane (o-BioCWHCl)1 and decachloroneocarborane (ra-BioClioC2H2),2 respec-

Vibrational spectroscopy of carboranes and parent boranes and its capabilities in carborane chemistry

“…To rationalize this fact, one has to remember that the extra hydrogen is an equal and full participant in the cage formation, being involved in the united system of the polyhedron bonding. Deuteration of the extra hydrogen seems to change the eigenvectors of the skeletal modes with extra-hydrogen participation, causing anomalous isotope effects.148 3. Dicarba-nido-undecaborate Group as a Substituent Investigations of C-derivatives of dicarba-rado-un-decaborate158 show that, unlike the C-o-carboranyl group, the C-7,8-dicarba-mdo-undecaborate group is a strong donor of electrons, both by inductive and by resonance effects.…”
