摘要：

By electrochemical oxidation of [B6H5(CN)](2-) in the presence of nitrite ions and of the base DBU in dichloromethane solution Cis-[B6H4(CN)(NO2)](2-) and cis- [(CN)B6H4(NO)B6H4(CN)](3-) are formed and can be isolated by ion exchange chromatography on diethylaminoethyl cellulose. The crystal structure of the tetraphenylarsonium salt has been determined by single crystal X-ray diffraction analysis. [As(C6H5)(4)](2)-cis-[B6H4(CN)(NO2)] is monoclinic, space group P2(1)/a with a = 20.343(5), b = 10.896(2), c = 21.572(5) Angstrom and beta = 107.30(2)degrees. The B-11 NMR spectra are consistent with disubstituted octahedral B-6 cages with local C-2v symmetry. The IR and Raman spectra exhibit characteristic NO2, NO, CN, BH, and B-6 vibrations.
