In the ethylation of benzene with ethyl-1-<SUP>13</SUP><I>C</I> fluoride and ethyl-1-<I>d</I><SUB>2</SUB> fluoride in boron trifluoride hydrate, almost a 50% isotope position rearrangement in the ethyl group of ethylbenzene was found, whereas in the boron trifluoride-catalyzed ethylation in excess benzene no rearrangement was observed. Based on these results, it was suggested that an electrophile is an ethyl cation in the ethylation of benzene in excess boron trifluoride hydrate and a nonionized polar complex in the boron trifluoride-catalyzed ethylation in excess benzene.
