Treatment of 7-(CH3)3N-7-CB10H12 with triethylamineborane(3) at 180-200 °C proceeds under splitting off one methyl group and inserting one boron vertex to obtain 1-(CH3)2NH-1-CB11H11. Methylation of the latter compound produces 1-(CH3)3N-1-CB11H11 which can be reduced to the parent 1-CB11H12- anion with sodium in liquid ammonia. The constitution of all compounds was established by NMR and mass spectroscopy.
