The Al2I6-catalyzed iodination of 4,5-C2B4H8 produces the enantiomorphs 3-IC2B4H7 and 6-IC2B4H7. No HI was observed. The iodination of C2B4H6 with Al2I6 at 75C. similarly formed H2 and a 20 yield of 2-IC2B4H5. The nmr and mass spectra of these iodocarboranes were used for identification and structural understanding. Both carboranes resisted the action of mercury salts for the replacement of iodine from boron. The easily formed adduct IC2B4H5NCH33 probably is a new kind of quaternary ammonium salt. Author
