Notes:
An electron paramagnetic resonance (EPR) technique was used to show that simple alkyl radicals readily abstract hydrogen from 1,4-cyclohexadiene. Rate constants for the reaction were ca. 104-105 M-1 s-1 at 300 K and activation energies 5-7 kcal mol-1. For the stabilized radicals, allyl and benzyl, the rate constants were 〈102 M-1 s-1 at 300 K. The data suggest that 1,4-cyclohexadiene could be used as an effective trap to probe rearrangement reactions of carbon centered radicals and biradicals.
