Description
Kinetic isotope effect (KIE) measurements in the trans-alkylation of toluene and benzene with ethylbenzene in hexane in the presence of AlBr3 at 313 K indicate that deuterium in the toluene methyl group causes a small inverse KIE for a π-complex transition state. The small direct KIE found for the reaction with C2D5C6H5 does not agree with a mechanism involving alkyl- and α-phenylalkyl cations. (author)
