Reactions of cyclopentene with hydrogen or deuterium have been followed on zinc oxide in the temperature range from 324 to 371 K using gas chromatography or mass spectrometry and samples of the products have been examined by deuterium n.m.r. spectroscopy.With deuterium an exchange reaction occurs leading to the stepwise replacement of the two olefinic hydrogen atoms by a mechanism involving the formation of cyclopentenyl intermediates.Cyclopentane is also produced but a rate which is slower than the exchange of cyclopentene.The process is controlled by the rate of formation of cyclopentyl radicals which do not readily dissociate again to alkene.Deuterium n.m.r. spectroscopy has potential for identifying and estimating groupings of deuterium atoms in cyclopentane.
