Abstract

Rates of disproportionation of ethylbenzene and m-diethylbenzene have been measured in the solvent trifluoromethanesulfonic acid (triflic acid). Ethylbenzene disproportionates very rapidly, whereas m-diethylbenzene reacts at a conveniently measurable rate. The reactions obey ht-order kinetics over a wide range of concentration, and the results are interpreted as involving ethyl transfer to the triflate anion followed by alkylation via the ethyl triflate ...
