The title compound, C(13)H(12)N(2)O(2)S, was prepared by the reaction of 1-(2-hy-droxy-phen-yl)ethanone and thio-phene-2-carbohydrazide. The dihedral angle between the benzene and thio-phene rings is 10.07 (17)°. An intra-molecular O-H⋯N hydrogen bond may influence the mol-ecular conformation. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds into chains along [010].

Thiophene containing thiazolyl carbohydrazide on reaction with various aryl isothiocynates yields thiosemicarbazides which were transformed into 1,2,4- substituted thiazoles by Hantzsch synthesis and characterized spectral methods. Most of the synthesized new are found to be promisingly effective against tested bacterial strains exhibited moderate activitytested fungal strains. 1, 2,4- weakly a...

The reaction of 5-methyl-7-nitro-1H-indole-2-carbohydrazide with ethyl aceto-acetate yielded the title mol-ecule, C16H18N4O5, in which the indole ring is almost planar, with the greatest deviation from the mean plane being 0.006 (2) Å. The nine atoms of the indole ring are almost perpendicular to the mean plane through the ethyl acetate group, as indicated by the dihedral angle of 87.02 (4)° be...

The title compound, C17H18N4O2S·CH3OH, was synthesized by the condensation reaction of o-meth-oxy-benzaldehyde with thio-carbohydrazide in methanol. The two benzene rings are inclined each to other at 31.7 (1)°. Inter-molecular N-H⋯O and bifurcated O-H⋯N(S) hydrogen bonds link two thio-carbonohydrazide and two solvent mol-ecules into a centrosymmetric unit. These units, related by translation a...

The title compound, C13H12N4O2, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. Mol-ecule B is planar to within 0.044 (3) Å for all non-H atoms, while mol-ecule A is slightly twisted, with a dihedral angle of 6.29 (4)° between the mean planes of the pyrazine-2-carbohydrazide and 1-(2-hy-droxy-phen-yl)ethanone moieties (r.m.s. deviations = 0.0348 and 0.0428 Å, resp...

In this study some new o-benzimidazol-2'-yl-benzamido-p'-benzamido-2-phenyl-4-substituted phenyl-5-oxo-Imidazolines 3a-3j were synthesized. To synthesized target molecules we used various substituted oxazolone derivatives, synthesized from substituted benzaldehyde with hippuric acid. Substituted oxazolones 2a-2j were reacted with carbohydrazide derivative of benzimidazole 1 in presence of pyrid...
