Synchronous concerted bond heterolyses in the solvolysis of substituted benzyl azoxyarenesulphonates and characterization of the transition state
Abstract
Hammett parameters[ρ(σx+)=–3.27 and ρ(σY)= 1.07] for the solvolysis of a range of substituted benzyl azoxyarenesulphonates in 1 : 1 (v/v) trifluoroethanol–water indicate that the rate-determining fragmentation is a synchronous concerted process.
