Carboranes are polyhedral boranes in which a BH? unit has been formally replaced by an isoelectronic CH unit. An entire class of carboranes can be prepared from an alkyne and a borane by pyrolysis or by reaction in a silent electric charge.The general formula of carboranes is represented by C2BnHn+2, in which n is an integer; carboranes with n ranging from 3 to 10 have been characterized.
The carboranes have polyhedral molecular structures based on networks of boron and carbon atoms, in which the carbon atoms occupy adjacent positions. As a result, the structures of carboranes and their derivatives are similar to those of the isoelectronic (possessing the same number of electrons) polyhedral boranes, and, like the boranes, they involve three-centre bonds as well as ordinary two-centre bonds. Their most significant structural feature is the covalent bonding of carbon simultaneously to five or six other atoms.
The following borane and carborane derivatives have been supplied over kilograms. Most of them are available from warehouse.
