资源简介：
The carbene-stabilized electron-rich
iminocarboranyl boron(I) compound [(Dipp)NC(But)C2B10H10]B(NHC) (1) (Dipp = 2,6-diisopropylphenyl, NHC = 1,3-diisopropyl-4,5-dimethylimidazol-2-ylidene)
is an excellent precursor for the preparation of the unprecedented
carborane-fused azaborolyl radical cation [{(Dipp)NC(But)C2B10H10}B(NHC)]•+ ([2]•+) and dicarbollyl-fused
azaborole 7,8-nido-C2B9H9-7,8-C(But)N(Dipp)B(NHC) (3) via controlled single-electron oxidation and two-electron
oxidative deboration, respectively. Single-crystal X-ray analyses
and DFT calculations indicate that the unpaired electron in [2]•+ is delocalized over the BNC unit, and
the two fused five-membered rings in 3 form a sort of
π-conjugated system.
