Abstract
The 1,2-bis(dialkylamino)benzene radical cations 2a-c(.+) were generat ed by oxidation of the parent compounds with iodine or lead tetraaceta te. ESR and ENDOR studies of 2a(.+) and 2b(.+) gave evidence of a rest ricted rotation about the C-NMe(2) bond; based on the results of 2c(.) the different N-methyl proton splittings in 2a(.+) and 2b(.+) were a ssigned to the exo and endo N-methyl groups.
