| Abstract: | Reductive amination of 4′-formylbenzo-15-crown-5] with sodium cyanoborohydride in the NH4Ac/MeOH medium followed by acid addition and extraction with CHCl3 unexpectedly lead to the isolation of the salt (B15C5-CH2-NH3)+-(H3BCNBH2CN)− with an unusual dicyanodiborohydride anion. The self-complementary 4′-ammoniomethylbenzo-15-crown-5] cation was found to exist as a supramolecular dimer in the solid state, acetonitrile solution, and gas phase as revealed by X-ray crystallography, NMR and mass spectrometry, respectively. |
