- A computational study of the fluctional behaviour of group 14 substituted ortho -semiquinone radicals
-
The dynamics of the 1,4-migration of some O-substituted 3,5-di-tert-butyl-ortho-semiquinone radicals have been calculated by density-functional theory (DFT). There is very good agreement in the rate constant and Arrhenius parameters between these calculations and experimental values for migration of H, D, and the Me3Si group. For the Me 3Sn group, the calculations indicate an incredibly fast migration (k293K = 2.0 × 1012 s-1), a result that is consistent with experimental data (k293K > 109 s-1). Other O-substituents examined by DFT and compared with experimental data were H3C and Me2ClSn.
