Abstract:

Direct chlorinations of carborane and neocarborane result in undecachlorocarborane B10Cl10C2HCl and decachloroneocarborane neo-B10Cl10C2H2, respectively, as the ultimate products. To achieve perchlorination, it became necessary to devise other methods to introduce the additional chlorine atoms. Since B10Cl10C2HCl and neo-B10Cl10C2H2 are carbon acids of acidity comparable to nitroform, and since KCNO23 reacts readily with chlorine to form ClCNO23, it was suspected and confirmed that metal and ammonium salts of polychloro-carboranes and -neocarboranes react similarly to give the perchlorinated compounds in almost quantitative yield. In addition it was discovered that direct substitution of B10Cl10C2HCl could be effected with N-chlorosuccinimide. Author
