The new isocyanato carboraneanion, [7-OCN-7-CB10H12]− was prepared by the reaction of 7-H3N-7-CB10H12 with triphosgene in the presence of triethylamine. The structure of this compound was established by 1H, 11B and 13C NMR as well as IR spectroscopy. The reactivigty of this compound with a series of organic amines was investigated. The resulting ureas were obtained in good to excellent yields. This
