Abstract
Reaction of icosahedral carboranes with excess sulfur over AlCl3 converts in high yields o-carborane to 9,12-, and m-carborane to 9,10- and 5(4),9-dithiols which were transformed by CH2Br2 to the appropriate cyclic thioformal derivatives. Reaction of 9,12(HS)2-1,2-C2B10H10 with acetone and AlCl3 afforded a cyclic thioketal, the structure of which was confirmed by X-ray structure analysis. All structures were proposed on the ground of 1H-, 11B-NMR and mass spectra.
