Decaborane halogenated at the 6-position (6-X-B10H13 , X = Cl, Br, I) was synthesized through cage-opening reactions of closo-B 10H102– induced by treatment with hydrogen halides absorbed in ionic liquid mixtures known to greatly enhance HX acidity. The previously unknown member of the 6-halogenated series, 6-F-B10H 13, was synthesized in excellent yields by reaction of the closo-B 10H102– with triflic acid in the presence of 1-fluoropentane. Triflic acid also induced the cage-opening of closo-B 10H102– to 6-Cl-B10H 13 when performed in CH2Cl2. The 6-halogenated isomers were used as starting materials in the syntheses of 5-X-B10H13 (X = Cl, Br, I). Base catalyzed isomerization reactions yielded equilibrium mixtures of 5-X-B10H13 and 6-X-B10...
