The analysis of formation routes of products suggested the contribution of some other isomers in addition to a well-known candidate, acenaphthylene, in the mass peak at m/z = 152 (C12H8). The most critical point we should remember is that like oxidation state assignments, electron counting is a formalism and does not necessarily reflect the distribution of electrons in the molecule. Reactions of o-benzyne with propargyl and benzyl radicals: potential sources of polycyclic aromatic hydrocarbons in combustion. This reaction cannot occur if the metal center of the complex doesn't have accessible two units higher than the initial oxidation state. Shaozhuan Xiong, Jun Li, Jingbo Wang, Zerong Li, Xiangyuan Li.
