  the C4B8 compounds were found to have nonrigid stereochemistries; both the 11B and 13C NMR spectra of the “carbons apart” compounds consisted of single resonance peaks, indicating rapid atom equilibration on the NMR time scale. The “carbons adjacent” compounds showed 11B NMR spectra of six resonance peaks; each had a different chemical shift and peak-area ratio pattern. The 11B NMR spectra of the “carbons

  (V). Further alkylation of the sodium compound of V proved unsuccessful, either no reaction was found or inseparable mixtures were obtained. The overall yield of V was about 20%, based on the starting I. Compound III was found to undergo the typical reactions of deprotonation, to give 1-Na(THF)-5-(i-C4H9)-2,3-(SiMe3)2-2,3-C2B4H4 (VII) and oxidative cage closure, to produce closo -3-(i-C4H9)-1,2-(SiMe3)2-1
