✦ Synopsis

The titled quinone compound has been synthesized, and life X-ray ca'yslallographie a~alysis of this compound revealed that it has anti-anti-configuration for stereochemical relationship between two methylene and sulfur bridges. Its 1H and 13C NMR spectra in D2SO 4 inticate that the cationic species formed by protonation has localized positive charges on the carbony carbons, mainly due to the unfavorable p-orbital overlap. 6) 1997 Elsevier Science Ltd.
