The rigorous interpretation of kinetic and isotopic data leads to a detailed mechanism for C1-homologation chain growth and shows how product selectivities of acid-catalyzed hydrocarbon reactions are influenced by molecular structure and the stability of carbenium ion transition states for relevant methylation, hydride transfer, β-scission, and isomerization steps.
