Stereochemical relation between the migrating group on the ammonium nitrogen and the carbanion was investigated on Stevens rearrangement of N,N-dialkylbenzothiazolinium salts to show large migratory aptitude of the ethyl against the methyl group (Et: Me > 20:1), where cyclic ammonium ylide with planar π-type carbanion was proposed to be the intermediate.
