3-(4′-Pyridyl)-4-amino-5-mercapto-1,2,4-triazole(1)reacted with aroyl isothiocyanates 2a-1 to yield twelve novel 3-(4′-pyridyl)-6-aroylamino-S-triazolo[3,4-b]-1,3,4-thiadiazoles,4a-1. Triethylamine was necessary for the condensation of 1 with phenyl isothiocyanate(3)to give 3-(4′- pyridyl)-6-phenylamino-S-triazolo[3,4-b]-1,3,4-thiadiazole(6).The structures were confirmed by the elemental and spectral analyses.Their antibacterial activity against B.Subtilis,E.Coli,E. aerogenes and S.aureus was observed preliminary.

A rhodium-catalyzed denitrogenative carbonylation of 1,2,3-thiadiazole with alkynes to construct(benzo)thiochromenones is developed.Both terminal and internal alkynes were compatible in this[3+2+1]cycloaddition,affording a broad range of poly-substituted thiochromenones.Unsymmetrical alkyne substrates exhibited good regioselectivity.

Three novel thiadiazolo‐ferrocence derivatives containing long chain alkyl group were synthesized and characterized. The voltammetric behaviour of these thiadaizolo‐ferrocene derivatives was studied on gold electrode (diameter 1 mm) in CH 2 Cl 2 /0.2 mol/L tetra‐ n ‐butylammonium hexafluorophosphate. The influence of β ‐cyclodextrin on the voltammetric behaviour of the compounds was also studied.

Novel 1, 3, 4-thia(oxa)diazoles containing thienyl groups were synthesized. Analogous to the naturally-occurring compound, α-terthienyl, they can be photosensitized by ultraviolet light and showed phototoxicities against the 2nd instar larvae of southern armyworm (Pseudaletia separata Walker), they also showed photocleavage action to pBR322 DNA.

The principle of using amplification reactions of iodine was employed in this paper to estimate the thiadiazole derivatives on basis of their reactions with iodine I chloroform, removal of the excess iodine and determination of the resulting iodide, after oxidation to iodate. The overall reaction gave an amplification of the iodide that is (12) times larger for the compounds: 2-amino-5-mercapto-1,3,4-thiadiazole (I);2,5-dimercapto-1,3,4-thiadiaole (II) and 2,5-diamino-1,3,4-thiadiazole (III) and (36) times for 2,5-dihydrazino-1,3,4-thiadiazole (IV) and (6) times for 5-mercapto-2[(3[5’-nitro-2-’furyl]·methylene)amino]-1,3,4-thiadiazole (V) and 5-mercapto-2[(3[5’-nitro-2-’furyl]-prop-2-enylidene)amino]-1,3,4-thiadiazole (VI). By titration, 1-mL of standard thiosulfate solution was found equivalent to 0.108 mg of (I);0.126 mg of (II), 0.16 mg of (III), 0.041 mg of (IV), 0.40 mg of (V) and 0.435 mg of (VI). Using the spectrophotometric detection for the amplification reaction gave high absorbance values at 605 nm for the blue starch-iodine complex. Beer’s law was obeyed up to 4.0 ppm for compounds (I and II);6.0 ppm for compounds (III, IV and VI) and 5.0 ppm for compound (V). The mechanism of the reactions was proposed and the analytical parameters were evaluated for both methods. The method was applied for synthetic samples of industrial importance. The recovery was comparable while the sensitivity and detection limits were better for the spectrophotometric detection.
