✦ Synopsis

The number and dimeric nature of the components of a commercial mixture of methylcyclopentadiene dimers was established by capillary gas chromatography on different stationary phases and temperatures of 80 and 100°C. The mixture was later fractionated by preparative gas chromatography into fractions containing pure or major components. Some of the dimers are transformed into isomers with an exocyclic double bond. The assignment of structures was carried out on the basis of nuclear magnetic resonance spectroscopic data for the dimers and iso-dimers.
