Abstract

Twenty-two salts of the type p-YC6H4NMe2R+-03SC6H4X@) were synthesized. R= Me, Et; X= CH3, C1, Br, NO2; Y= H, Br. These salts exist as ion pairs in dilute solutions in octanoic acid. Eight salts were soluble enough to permit measurement of ion-pair dipole moments. Analysis indicates that, in the ion pairs, the N+ center of the cation is adjacent to one of SO3- oxygen atoms. Preliminary results for infrared S-0 stretching frequencies in the free anions ...
