The C6H5 + C2H2/C2H4 addition reactions and subsequent transformations were studied within a framework of the G2M composite method. The detailed search on the corresponding potential energy surfaces revealed that chemically activated adducts could undergo several isomerization pathways in competition with well-known deactivation and H-elimination channels. Thus formed isomeric (vinylic/aliphatic, aromatic and bicyclic) C8H7/C8H9 radicals could serve as active agents in the mass growth reactions with C2H2, C2H4, and other light unsaturated hydrocarbons and radicals. The latter processes are relevant to the PAH formation in hydrocarbon combustion. The mechanism of the C6H5 + C2H2/C2H4 addition reactions in different regimes and the implications to larger scale combustion modeling were discussed. Original is an abstract.
