3-(Arylimino)-5-(phenylbenzylidenehydrazido)-1,2,4-dithiazolidines: oxidative debenzylation and cyclization of 1-(phenylbenzylideneamino)-5-aryl-2-S-benzyliso-4-thiobiurets

Abstract

the cosphere of the ion with respect to the bulk solvent should increase the viscosity around the ion, and, therefore, Its mobility should diminish (descending line in Figure 1).From the 7+°v alues In the present work (by using eq 2) and the limiting equivalent conductances, A0, known previously (4), limiting ionic conductances have been determined (Table II).

Synthesis of some 3-(arylimino)-5-(ethylethylidenehydrazido)-1,2,4-dithiazolidines

“…All of these compounds gave elemental analysis (C, , N, S) within ±0.40% of the calculated values.1,2,4-dithiazolidenes (TableII) and 1 -(ethylethylldeneamino)-5aryl-2,4-dithloblurets (TableIII) were synthesized by the procedure reported earlier(1)(2)(3).…”
