Ab initio and density functional calculations predict that intramolecular homolytic substitution reactions of oxyacyl radicals at the selenium atom in omega-alkylseleno-substituted radicals proceed via mechanisms that do not involve hypervalent intermediates. When the leaving radical is tert-butyl, energy barriers (Delta G(+)(+)) for these reactions range from 27.1 (G3(MP2)-RAD) kJ mol(-1) for the formation of the five-membered cyclic selenocarbonate (6) to 41.5 kJ mol(-1) for the six-membered selenocarbonate (8). G3(MP2)-RAD calculations predict rate coefficients in the order of 10(5)-10(8) s(-1) and 10(2)-10(5) s(-1) for the formation of 6 and 8, respectively, at 298.15 K in the gas phase.
