The Cobalt bis(1,2-dicarbollide) anion is a weakly coordinating anion [1] It is the most studied dicarbollide complex.
Properties
editIs amphiphilic, forms vesicles in water. Weakly coordinating High stability
Synthesis
editSynthesis usually starts with degradation of o-carborane with base to form nido-[7,8-C2B9H11]- which is then deprotonated to form the 1,2-dicarbollide dianion, which reacts with cobalt chloride to produce the cobalt bis(1,2-dicarbollide) anion.
Reactions
editCan be reversibly undergo two one electron reductions, and one one electron oxidation. Can be singly or doubly deprotonated by butyl lithium. Degraded to something something by alkali
Halogenation
editHalogenated derivatives are far less reactive.
Uses
