Abstract
Di- and tetraprotonation of oligoamines 1-3 pocessing bicyclo[3.1.O]he xyl linking blocks were investigated by C-13 NMR spectroscopy and the location of the protons in the resulting salts was determined via (1)J (CH) coupling constants. The NMR spectroscopic prediction was confirme d by X-ray structural analysis in the case of the diammonium salt 2 . 2 TFSA hexahydrate (TFSA, trifluoromethanesulfonic acid); intramolecul ar hydrogen bonding was established in the solid state.
