It is known3 that the disproportionation4 of ethylbenzene to give benzene and a mixture of di-and triethylbenzenes catalyzed by hydrogen bromide promoted aluminum bromide is much faster than the corresponding disproportionation of toluene. McCaulay and Lien3 have explained the huge rate difference o

## Abstract Transbromination of chlorobenzene and of toluene with bromobenzene under the influence of aluminium bromideβ[^82^ Br] is accompanied by some bromine exchange between organic and inorganic bromides. However, since many bromine atoms are __transferred__ for every bromine atom __exchanging
N M R spectra (in nitromethane, TMS as internal standard) of ( 2) include bands at T = 3.5-5.0 (unseparated multiplet due to the ring protons at C-4 and C-5 and the vinyl protons), as well as for (2), R = CH3 (obtained as an oil; stable for only a few days) T = 7.6 (CH3 protons) and for (2), R = C6H
