Study on the cyclic reaction between 1-benzoyl-3-arylthiourea and hydrazine hydrate;

2,5-Disubstituted-1,3,4-triazole derivatives were prepared by the reaction of hydrazine hydrate with 1-benzoyl-3-arylthioureas obtained from the reaction of benzoyl chloride, potassium thiocyanate and aniline, and their structures were confirmed by IR, 1H NMR and HRMS spectra.

In this thesis, 1-aryl-3-benzoyl-2-thioxoimidazolidin-4-one, 1-aryl-3-benzoyl-5-chloro-2-thioxoimidazolidin-4-one and 1-ary-2-thioxoimidazoli-din-4,5-dione were prepared by the reaction of 1-benzoyl-3-arylthiourea with chloroacetyl chloride, dichloroacetyl chloride, oxalyl dichloride.

The reaction of 1-aryl-3-benzoyl thioureas with chloroacetic chloride was studied, and 1-aryl-3-benzoyl-2-thioxo-4-imidazolones were synthesized.

Three new aroylthiourea receptors were synthesized.

Synthesis and characterization of N-[(2-(carboxyl-1,3,4-thiodiazol)-5-yl]-N'-aroyl thioureas;

Synthesis of the aroyl thiourea derivatives as novel small molecule inhibitors of cysteine protease of Trypanosomal cruzi;

In order to find high biological active pesticide, eighteen novel aroyl thioureas and aryloxyacetyl ones have been synthesized by the reaction of 5-amino-1,3,4-thiadiazol-2-carboxylic acid with aroyl isothiocyanates and aryloxyacetyl isothiocyanates, with their structure confirmed by IR, 1H NMR spectra and elemental analysis.
