Abstract
Inter-and intraradical mechanisms that promote deuterium-hydrogen scrambling in labeled cyclopentene-d, are investigated at 800 and 1200 K. Rate constants are estimated for each step and for possible competing side reactions. The fast radical bimolecular exchange at 800 K and unimolecular scrambling at 1200 K of labeled cyclopentene are shown to be faster than the Woodward-Hoffman allowed 1, 4 concerted molecular elimination of ...
