ABSTRACT

1,3-Diethoxy-4,6-di(ethoxymethylene)-5,5-dimethylcyclohexenylium perchlorate (6a) was synthesized from 1,3-diethoxy-5,5-dimethylcyclohexenylium perchlorate by successive introduction of ethoxymethylene groups. Perchlorate6a was also obtained from dimedone in one preparative step. Compound6a was studied by X-ray diffraction analysis. The bond lengths in the fragment containing the C(1)–C(4) and C(6) atoms of the six-membered ring of the cation are substantially equalized and close to the Carom-Carom bond length. Apparently, this fact indicates that the positive charge is primarily delocalized over the aromatic system. More... »
