Consistent with our hypothesis for a mechanism involving two kinetically-distinct diradical intermediates, the observed effects of styrene α-substituents can be explained as deriving either from steric effects or radical stabilizing effects.
与我们关于涉及两个动力学上不同的双自由基中间体的机理的假设相一致,可以将所观察到的苯乙烯α-取代基的作用解释为源自空间作用或自由基稳定作用。
