Methyl Camouflage in the Ten-Vertex Closo-Dicarbaborane(10) Series. Isolation of Closo-1,6-r2c2b8me8 (R = H and Me) and Their Monosubstituted Analogues.

Reported are procedures leading to the first types of methyl camouflaged dicarbadecaboranes with fewer than eleven vertices. The compounds contain the closo-1,6-C2B8 scaffolding inside the egg-shaped hepta - decamethyl sheath, which imparts unusually high air and solvolytic stability to all of these compounds.
