Abstract

X-Ray study of the four title compounds has shown that the strong lowering in the basicity of the acenaphthylene proton sponge 2 in comparison with its acenaphthene counterpart 1 is due to pronounced conjugation between the NMe2 groups and the π-electronic system of the molecule rather than to the nature of intramolecular hydrogen bonding in the protonated forms. The first X-ray structure of the acenaphthylene derivative is reported.
