摘要：

Rate constants and Arrhenius functions for ring openings of the (trans-2-ethoxycarbonylcyclopropyl)methyl radical and the (trans-2-tert-butoxycarbonylcyclopropyl)methyl radical were determined by the PTOC-thiol method with PhSeH trapping. At 25 degrees C, these radicals rearrange with rate constants of 7 and 12 x 10(10) s(-1), respectively.
