Experimental manipulations were carried out using standard vacuum and inert atmosphere techniques. All chemicals were obtained from Sigma-Aldrich and used as received. closo-1,12-Dicarbadodecaborane was purchased from Katchem Ltd., E. Krásnohorské 6, 110 00 Prague 1, Czech Republic. Diethyl ether and THF were dried over Na metal and NaK, respectively, and distilled fresh prior to use. Deuterated solvents were obtained from Cambridge Isotopes Laboratories and used as received. NMR spectra were recorded either on a Varian INOVA 500 spectrometer at 500 MHz or a Bruker Avance-III 300 spectrometer at 300 MHz. Chemical shifts are given in ppm with positive shifts downfield: all 1 H and 13 C chemical shifts were referenced relative to internal residual protons from a lock solvent. For 11 B decoupled 1 H NMR spectra, the decoupling was not complete and BH proton peaks did not integrate to expected values. The values listed are the actual values observed and the expected values are in brackets. IR spectra were recorded eith a Nicolet Nexus 670 FT-IR spectrophotometer either in KBr pellets or neat compound deposited onto a Ge window. Mass spectra were recorded using a Thermo Finnigan Polaris Q GC/MS instrument using a Phenomenex ZB-5ms general purpose column (30 m, 0.25 mm ID, 0.25 um film thickness, max. 320 ºC isotherm/340 ºC program) in electron impact (70 eV) ionization mode. Elemental analysis was performed by Columbia Analytical Services, 3860 S. Palo Verde Road, Suite 302, Tucson, AZ 85714. closo-1-Iodo-1,12-dicarbadodecaborane 1. The synthesis of 1 was adapted from a literature procedure. 1 To a flame-dried round bottom flask were added p-carborane (0.2 g, 1.39 mmol) and anhydrous diethyl ether (5 mL). The solution was stirred at room temperature under nitrogen while n-BuLi (1.6 M, 1.6 mmol, 1.0 mL) was added dropwise from a syringe. The reactants were stirred for
