The polyhedral B6C2H8, B7C2H9, and B8C2H10 carboranes and their C-monomethyl and C-monophenyl derivatives

The pyrolysis of 1,3-B7C2H13 at 215° in the absence of diborane yields the B6C2H8, B7C2H9, and 1,6-B8C2H10 carboranes, while in the presence of diborane the yield of 1,6-B8C2H10 is considerably enhanced. Isomerization of 1,6-B8C2H10 to the 1,10-B8C2H10 isomer occurs at 300°. Pyrolysis of 1,3-NaB7C2H12 at 200° yields 1,7-B7C2H9. The C-monomethyl and C-monophenyl derivatives of these carboranes are also described.
