Conclusions
-
1.
In the presence of AlCl3, CH3Br, CH3I, and C2H5Br alkylate o- and m-carborane at the boron atoms in the carborane ring, with the formation of B-alkyl-o- and B-alkyl-m-carboranes, consisting of from one to eight alkyl groups per molecule.
-
2.
In the presence of AlCl3, the reaction of i-C3H7Br with o- and m-carborane leads chiefly to the formation of the corresponding B-mono-, diisopropyl-o-, and diisopropyl-mcarboranes.
-
3.
In the presence of AlCl3, arsacarborane and phosphocarborane react with C2H5Br. Alkylation at the boron atoms of the carborane ring takes place.
-
4.
In the presence of AlCl2, cyclopentadienyldicarbolylcobalt reacts with CH3I, C2H5Br, and i-C3H7Br, undergoing alkylation as well as halogenation at the boron atoms of the carbonate ring.
