Abstract
The radical CH3CH [graphic omitted] N [graphic omitted] NC2H5(1) was produced in the di-tert-butyl peroxide-initiated and thermal decompositions of azoethane. Self-combination of 1 takes place almost exclusively at the carbon radical centre (1C). The disproportionation: combination ratio Δ(Ċ2H5, 1N)≈ 0.38 (Δ=kd/kc) and the rate constant ratio kb(ĊH3, 1N)/kc(ĊH3, 1C)= 0.15 ± 0.03. The cross-combination ratio ϕ(ĊH3, 1C)= 1.38 ± 0.11, which is lower than the cross-reaction ratio ϕ*(ĊH3, 1)≈ 2.5.Keywords
