Abstract: | Although alkenyl radicals are important intermediates involved in both alkanes and alkenes combustion, previous kinetic studies on them are very limited, especially for the long‐chain alkenyl radicals. To deeply investigate unimolecular reaction activities of long‐chain alkenyl radicals, a series of octenyl (C8H15) radicals were chosen to study the reaction kinetics of three typical types of reactions (i.e., intramolecular radical addition, internal H‐migration, and bond dissociation) in this work. The CBS‐QB3 method was used to build potential energy surfaces for these reactions, and the transition state theory was applied to obtain the high‐pressure limit rate constants. Some general rules are observed from our systematic calculations in respect of structure–activity relationships. |
