Abstract:

When the carbons of carborane participate in exocyclic rings of O, N and Si atoms the thermal rearrangement of the ortho carborane nucleus to the meta configuration is opposed. These molecules as a whole therefore resist degradation at elevated temperature. Chemically these cyclics are stable under acid conditions but the siliconcarborane carbon bond is attacked by bases. Additional types of cyclic silazanes are reported and reactions of some functional groups at the silicon atoms are described. Author
