چکیده
The title compound, C(8)H(9)ClN(4)S, which has potential insecticidal activity, was synthesized by the reaction of 2-chloro-5-methyl-nicotinaldehyde and thio-semicarbazide. In the crystal structure, the mol-ecules are linked via inter-molecular N-H⋯N, N-H⋯S and N-H⋯Cl hydrogen bonds, forming a three-dimensional network stacked down a.

In this work 3-chloro-2-chlorocarbonylbenzo[b]thiophene (1) was prepared from cinnamic acid and then converted into the acid hydrazide 2. The azomethines 3a-e were prepared from the corresponding aryl aldehydes and the acid hydrazide 2. Treatment of compound 2 with formic acid gave the N-formyl acid hydrazide 4, which upon refluxing with phosphorous pentoxide or phosphorous pentasulphide in xyl...
متن کامل1-(4-Chlorobenzoyl)-3-(3-methylpyridin-2-yl)thiourea
The mol-ecule of the title compound, C(14)H(12)ClN(3)OS, consists of three approximately planar fragments: the central thio-urea group, the chloro-phenyl group and the picolyl (3-methyl-pyridin-2-yl) group with a maximum of 0.035 (2)° for an N atom from the mean square plane of the central thiourea group. The central fragment forms dihedral angles of 33.30 (8) and 76.78 (8)° with the chloro-phe...
