New representatives of 3-alkyl-5-amino-2-imino-1,3,4-thiadiazolines (alkyl=C5H11, C10H21, C15H31) were synthesized by alkylation of 2,5-diamino-1,3,4-thiadiazole with corresponding alkyl bromides. Their condensation with 1,1-dimethoxy-3-iminoisoindoline led to new three-units products of ABA-type – 1,3-bis[(3-alkyl-5-amino-1,3,4-thiadiazol-2(3H)-ylideneamino)]-2H-isoindoles. These compounds were characterised by IR, UV-vis, and NMR spectroscopy, mass-spectromery, data of elemental analysis.
