Tin(IV) Complexes with Thiosemicarbazide and 4‐Methyl‐3‐thiosemicarbazide Derivatives
Zeitschrift für anorganische und allgemeine Chemie, 2007AbstractFive new complexes were isolated from a CH2Cl2 solution of SnCl4 and the ligands benzil bis(thiosemicarbazone) L1H6, benzil bis(4‐methyl‐3‐thiosemicarbazone) L1Me2H4, 5‐methoxy‐5,6‐diphenyl‐4,5‐dihydro‐2H‐[1,2,4]‐triazine‐3‐thione, L2H2OMe and 5‐methoxy‐4‐methyl‐5,6‐diphenyl‐4,5‐dihydro‐2H‐[1,2,4]‐triazine‐3‐thione, L2MeHOMe.

Hydrogen bonding in thiosemicarbazide
Acta Crystallographica Section B Structural Crystallography and Crystal Chemistry, 1970In a recent paper (Domiano, Fava Gasparri, Nardelli & Sgarabotto, 1969, DGNS) the crystal-structure analysis of thiosemicarbazide, carried out by photographic methods, was reported (final R=9 .9%) . The positions of the hydrogen atoms were postulated from consideration of the hybridization of the nitrogen atoms and the packing interactions, no direct ...

Susceptibility to audiogenic seizure induced by thiosemicarbazide
Experimental Neurology, 1969Abstract Rats, cats, and monkeys were subjected to audiogenic stimuli after the administration of thiosemicarbazide (TSC). The treated rats responded to audiogenic stimulation with episodic running behavior (ERB) with or without convulsion (C), the most effective dosage being 4.4 mg/kg.

Menthone Semicarbazides and Thiosemicarbazides as Anticonvulsant Agents
Medicinal Chemistry, 2010A series of novel (+/-) 3-menthone semi carbazides (1-7) and thiosemicarbazides synthesized using an appropriate synthetic route and characterized by thin layer chromatography and spectral analysis. The anticonvulsant activity of synthesized compounds was established after intraperitoneal administration in three seizure models in mice which include ...

A reinvestigation of the cyclodesulfurization of thiosemicarbazides
Journal of Heterocyclic Chemistry, 1981AbstractA recent report describing the preparation of 2‐(substituted‐amino)‐3,4‐dihydro‐5H‐1,3,4‐benzotriazepin‐5‐ones (3), by the cyclodesulfurization of hydrazides prepared from o‐aminobenzoylhydrazine (1) and isothiocyanates, is erroneus. The products resulting from this reaction sequence are, instead, 2‐(substituted‐amino)‐5‐(o‐aminophenyl)‐1,3,4 ...

Oscillating chemiluminescence with thiosemicarbazide in a batch reactor
Luminescence, 2008AbstractOscillating chemical reactions are complex systems involving a large number of chemical species. In oscillating chemical reactions, some species, usually reaction intermediates, exhibit fluctuations in their concentration. In this report, a novel slowly‐damped oscillating chemiluminescence produced by the addition of thiosemicarbazide (TSC) to ...

Laser Desorption and Ionization of Thiosemicarbazides
Colloid Journal, 2020Ionized products of desorption of thiosemicarbazides from a steel target surface before and after deposition of solid solutions of thiosemicarbazides in organic matrices (nicotinic acid, α-cyano-4-hydroxycinnamic acid, 2,5-dihydroxybenzoic acid, and dithranol) onto it have been studied by mass spectrometry.

The assignments of the in-plane vibrations of the ionic and neutral nickel(II) thiosemicarbazide complexes, Ni(Htsc)2Cl2 and Ni(tsc)2, and their deuterated molecules have been made with the aid of normal coordinate treatments. The out-of-plane vibrations have been assigned empirically.
