SYNTHESIS, CHARACTERIZATION OF SOME MANNICH BASE NEW 1, 3, 4- OXADIAZOLE-2-THIONE DERIVATIVES SYNTHESIS, Charakterisierung einiger Mannichbase NEU 1, 3, 4 - Oxadiazol-2-thion DERIVATE

Two new oxadiazole compounds 3,3 -[methylin-bis(1,4-phenyline-iminomethyline]-bis-(5- phenyl-1,3,4-oxadiazol)-2,3(H)-thione and 5-phenyl3-[4-(5-phenyl-1,3,4-oxadiazole-3yl) methyl]amino}phenyl)amino]methyl1,3,4-oxadiazolidine-2-thione thiooxamethane have been synthesized. The reaction was done in pH= 7 and in presences of amin molecules by Mannich reaction. The structures of the compounds were characterized by FT-IR,13 C NMR and 1H NMR techniques.
