Some recent advances in the chemistry of dicarba-closo-dodecaboranes

Experimental data on the mutual rearrangements of isomeric dicarba-c/osododecaboranes( Reactions involving electron transfer to dicarba-closo-dodecaboranes(l2), and the properties of the resulting dodecahydrodicarba-nido-dodecaborates(2-) as intermediates of the rearrangements of 1.7and 1,12-dicarba-closo-dodecaboranes(l2) are discussed. Attention is also paid to the introduction of an NH 2 group into 1,2-dicarba-closo-dodecaborane(12) via the formation of dodecahydro-1,2-dicarba-nido-dodecaborate(2-) and to the reactions of 3-amino-1,2-dicarba -closo-dodecaborane( 12).
