Mechanism of Oxidative Debenzylation in lsodithiobiuret System : Preparation of some new 5-Diaryl/Arylalkylamino-3-Aryl/ Alkyl-I mino-1 ,2,4-Dithiazolines by the Oxidative Debenzylation of 1,1 ,5,-Trisubstituted-2-S-Benzyliso-4-Thiobiurets

Preparation of 5-ethylphenylamino-3-p-Cl-phenyl-imino-, 5-ethylphenylamino-3-p-tolylimino-, 5-ethyl-phenylamino-3-benzylimino-, 5-diphenylamino-3-p-Cl-phenylimino, 5-diphenylamino-3-benzylimino-1, 2, 4-dithiazolines has been described by the oxidative debenzylation of the corresponding 1, 1, 5-trisubstituted-2-S-benzyliso-4-thiobiurets. Mechanism of the reaction has been discussed.
