A new series of organoboranes. V. Some chemistry of cyclic silyl carboranes

Article abstract of DOI:10.1021/ic50020a023

When the carbons of carborane participate in exocyclic rings 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 silicon-carborane 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.
