EPR Investigations of Ring Chlorinated 4-DimethylaminophenylcationsThe influence of the position and the number of chlorine atoms in the ring of 4-dimethylaminophenylcations on the zero-field-splitting(zfs) parameter Dis investigated. It was found that the π-donor ability of the chlorine atom(s) ind 2(6)-position(s) increases the zfs parameter D. In the case of 3(5)-substitution the value of D decreases because of the steric hindrance of the dimethylamino-group.
