WebDec 9, 2024 · Simple primary aliphatic alcohols, such as butanol, cannot form a phenonium intermediate; therefore, these substrates must react through a different mechanism. In this case, we have identified transition states where the protonation of butanol occurs in concert with the formation of the C–C bond with mesitylene (Scheme 6 B).
