Abstract

Releasing carbon: Deprotonation of the amino group of the [1-H2N-closo-CB11F11] anion results in a transformation of the carba-closo-dodecaborate cluster into a closo-undecaborate dianion. The rearrangement is accompanied by loss of a fluoride anion, and the C[BOND]N fragment is converted into a cyano ligand (see scheme).
