1,1′-Bis(ortho-carborane) undergoes mild deboronation in solution in the presence of water with formation of the [7-(1′,2′-closo-C2B10H11-1′-)-7,8-nido-C2B9H11]- (1) anion. The chlorination of 1 with N-chlorosuccinimide in acetonitrile proceeds highly regioselectively to give [7-(1′,2′-closo-C2B10H11-1′-)-9-Cl-7,8-nido-C2B9H10]- (2) as the main product, whereas its bromination and iodination with elemental
