✦ Synopsis

An electron paramagnetic resonance (EPR) technique was used to show that simple alkyl radicals readily abstract hydrogen from l,4-cyclohexadiene. Rate constants for the reaction were ca. 104-105 M-' s-' at 300 K and activation energies 5-7 kcal mol-'. For the stabilized radicals, ally1 and benzyl, the rate constants were <lo2 M-' s 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.

Rate constants have been measured for the reactions of the sulfate radical, SO4'-, with alkanes, alkenes, alcohols, ethers, and amines in 95% acetonitrile solution. The rate constants were in the range of lo6 L mol-l s-l for the abstraction reactions and lo7 -lo9 L mol-' s-l for the addition and ele

dicted rate constants are invariably dominated by a 'Reaction with N'). While AOP treats amides as amines, we expect amides to be less reactive than amines from the analogous relationship between esters and ethers (see [3] for OH rate constants): if amines are matched to ethers (both are highly reac
