The title compound, (C6H11)3PS (systematic name: tri-cyclo-hexyl-λ5-phosphane-thione), is a triclinic (P-1, Z' = 1) polymorph of the previously reported ortho-rhom-bic form (Pnma, Z' = 1/2) [Kerr et al. (1977 ▸). Can. J. Chem. 55, 3081-3085; Reibenspies et al. (1996 ▸). Z. Kristallogr. 211, 400]. While conformational differences exist between the non-symmetric mol-ecule in the triclinic polymor...

A simple, sensitive, accurate, and green spectrophotometric method for the determination of Cu(II) using newly synthesized reagent, 6-(2-methoxynaphthyl)-2,3-dihydro-1,2,4-triazine-3-thione (MNDTT), has been developed. MNDTT was synthesized based on the acylation of methoxy naphthalene and reaction of the product with amyl nitrite, which upon reaction with thiosemicarbazide yielded 6-(2-meyhoxy...

Coccidiosis is one of the most common parasitic diseases affecting many species of domestic animals. This disease has a major economic significance and the search for new compounds having anticoccidial activity is of great importance. In this article, different levels of protection from coccidian infection by Eimeria stiedae were developed in rabbits by treatment with compounds incorporating th...

A series of cyclic analogues of bioactive thiosemicarbazide derivatives have been synthesized as potential antimycobacterial agents. The 4-amino-1,2,4-triazole-5-thione analogues (Ia-f) were prepared by heating a mixture of thiocarbohydrzide and appropriate carboxylic acids. Reaction of thiocarbohydrazide with γ-ketoesters in the presence of sodium methoxide furnished triazolopyridazine derivat...

Tert-butyl carbazate (1) reacted with ammonium thiocyanate and phenyl isothiocyanate to afford the corresponding 5-tert-butoxy-4H-1, 2, 4-triazole-3-thiol (3) 5-tert-butoxy-4-phenyl-2H1, 2, 4-triazole-3(4H)-thione 5 respectively. Compound (1) also reacted with carbon disulfide and potassium hydroxide to afford 5-tert-butoxy-1, 3, 4-oxadiazole-2(3H)-thione 6. Treatment of 6 with methyl iodide, 2...

Seleniumand sulfur-containing compounds can act as antioxidants by binding copper. To determine how this copper coordination results in the observed antioxidant activity, biologically relevant Cu and Cu complexes with the formulae [Cu(dmit)3] + (3), [Cu(dmise)4] + (4a), and [TpmCu(MISeox)] (6) (dmise = N,N′-dimethylimidazole selone; dmit = N,N′-dimethylimidazole thione; MISeox = bis(1methylimid...

Reactions of copper(I) halides with imidazolidine-2-thione and 1-methyl-1,3-imidazoline-2-thione in dmso involved C-S rupture in aerobic conditions and yielded a sulfate bridged polymer, [Cu(II){eta(2)-N,N-(N(2)C(3)H(5))(2)S}(mu-O,OSO(2))(eta(1)-OH(2))](n) 1 and a sulfate chelated monomer, [Cu(II){eta(2)-N,N-(N(2)C(4)H(5))(2)S}(eta(2)-O,OSO(2))(eta(1)-OH(2))] 2 {N,N-(N(2)C(3)H(5))(2)S = 2,2'-th...

The asymmetric unit of the title compound, C(7)H(6)N(2)S, contains one half-mol-ecule; the C and S atoms of the C=S group lie on a crystallographic mirror plane. In the crystal structure, inter-molecular N-H⋯S hydrogen bonds link the mol-ecules.

Introduction: Oxidative stress and resulting lipid peroxidation are involved in numerous pathological conditions. For this reason, the role of antioxidants attracts attention radical-scavenging capacity many natural synthetic supplements drugs has been extensively evaluated. Material methods: In present study, seven N,N'-disubstituted benzimidazole-2-thiones with ester (1 - 4) hydrazide (5 7) s...
