Abaszadeh, Mehdi, Hassan Sheibani, and Kazem Saidi. "The Condensation of (Chlorocarbonyl)phenyl Ketene with Bisnucleophiles. Synthesis of 4-Hydroxy-5-phenylpyro-[2,3-c]pyrazol-6-ones and Formation of Pyrazolo[1,2-a]pyrazole-triones by Hydrogen Exchange in Unstable Mesoionic Compounds."

Abstract:
The addition of (chlorocarbonyl)phenyl ketene 2 to 5-alkylpyrazol-3(4H)-ones 1 led to the formation of 3-hydroxypyrazolo[1,2-a]pyrazole-dione/pyrazolo[1,2-a]pyrazole-trione derivatives 3. This is ascribed to hydrogen exchange in initially formed unstable, mesoionic pyrazolo[1,2-a]pyrazol-4-ium-5-olates. In contrast, condensation of the same ketene with 3-alkyl-1-phenyl-2-pyrazolin-5-ones 4 afforded 4-hydroxy-3-alkyl-1,5-diphenylpyrano[2,3-c]pyrazol-6-one derivatives 5. The latter reaction provides a new and rapid route to 4-hydroxy-2-pyrones fused to pyrazole rings, in good to excellent yields

The pyrazol-5-ylthiourea obtained from I and phenyl isothiocyanate undergoes base-catalyzed cyclization to give pyrazolo[3,4-d]pyrimidinethione derivative IX.

Abstract:
Pyrazoles have been studied for over a century as an important class of heterocyclic compounds and continue to attract considerable interest due to the broad range of biological activities they possess. The incorporation of the essential structural features of pyrazoles with a ferrocene moiety could provide new derivatives with unexpected and/or enhanced biological activities since several ferrocene derivatives have already been shown to be active against a number of tumors. For this reason, we investigated the synthesis of ferrocenyl-substituted pyrazoles, such as 1-alkyl/aryl-5-ferrocenylpyr

Abstract:
The bibliographic study of chalcones of the type 1,3-aryl(heteryl)propen-2-one with thiosemicarbazidic 4- and 1,4-disubstituted and thisemicarbazonic groups respectively gives us the information that they have a wide spectrum of biological activity, but methods of their synthesis are less described in the literature, and they became our object of study. 4,5-Dihydro-1-H-(pyrazol-3-yl)phenylhydrazinecarbothioamides 3a and 3b were obtained according to the following scheme:Reagents and reaction conditions: i, ii) 2-Py, 25oC – 24h, 90-95oC – 3h, 77-82%; iii) DMF, CH3COOH, 70-80oC, 2-3h, 60-63%.

Abstract:
This mini-review summarizes the kinetic data obtained for the substitution reactions of some palladium(II) complexes containing bis-pyrazolylpyridine derivatives as pincer-type ligands with biologically significant nitrogen- and sulfur-donor biomolecules as nucleophiles. Three structurally different palladium(II) complexes were selected: [Pd(L1)Cl]+(Pd1), [Pd(L2)Cl]+(Pd2) and [Pd(L3)Cl]+(Pd3) (where L1 = bis(2-(1H-pyrazol-1-yl)ethyl)amine, L2 = 2,6-bis(5-(tert-butyl)-1H-pyrazol-3-yl)pyridine, and L3 = 2,6-bis(5-(tert-butyl)-1-methyl-1H-pyrazol-3-yl)pyridine, while for the entering nucleophiles

Abstract:
The advent of blue-green IIVI semiconductor lasers is stimulating the research activity in more efficient frequency-conversions of III-V semiconductor-laser sources. In almost all cases of the conversions, inorganic materials are being used. On the other hand, organic materials have been developed and expected to give more efficiencies in the conversions because of their higher figures of merit in comparison with the inorganics.
