Abstract

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° C, these radicals rearrange with rate constants of 7 and 12× 1010 s− 1, respectively.
