This study was conducted to determine the rate of intramolecular degenerate rearrangement of cyclopentene (CP), presumably via reversible conversion to vinylcyclopropane (VCP).Cyclopentene-3-13C was synthesized and heated to 1200 K in a single-pulse shock tube and then analyzed by 13C NMR to ascertain the extent of migration of the 13C label to the 4-position.The very small amounts of migration observed were consistent with log k (CP -> VCP) = 15.7 - (16000/T).This rate constant for CP -> VCP is too small to account for the previously reported evidence of multiple channels for H2 elimination from CP.
