Synthesis and theoretical study of a new family of pyrazole derivative
(Elsevier B.V., 2024)
Improved Regioselectivity in Pyrazole Formation through the Use of Fluorinated Alcohols as Solvents: Synthesis and Biological Activity of Fluorinated Tebufenpyrad Analogs
(American Chemical Society, 2008-12)
The preparation of N-methylpyrazoles is usually accomplished through reaction of a suitable 1,3-diketone with methylhydrazine in ethanol as the solvent. This strategy, however, leads to the formation of regioisomeric ...
New Fluorinated Pyrazol and Uracil Derivatives: Synthesis and Biological Activity
(American Chemical Society Inc, 2009)
Both fluorinated pyrazoles and uracils are compounds that display very interesting biological activity. This chapter reviews recent work or our group in the development of synthetic strategies for the preparation of new ...

Regiospecific synthesis of 5-trichloromethyl-1H-pyrazole and 1H-pyrazole-5-carboxylic ester derivatives
(BENTHAM SCIENCE PUBL LTD, 2008)
Reaction of 1,1,1-trichloro-4-methoxy-3-penten-2-one (1) with hydrazines (2a-h) (NH2NHR, R = H, Me, t-Bu, Ph, 4-NO2-C6H4, C6F5, CO2Me, CONH2) under differing conditions regiospecifically affords different pyrazole derivatives, ...
Synthesis and antimycobacterial activity of new pyrazolate-bridged dinuclear complexes of the type [Pd(mu-L)(N-3)(PPh3)](2) (PPh3 = triphenylphosphine; L = pyrazolates)
(Elsevier B.V., 2014-10-01)
Binuclear compounds of the type [Pd(mu-L)(N-3)(PPh3)](2) {L = pyrazolate (1); 3,5-dimethylpyrazolate (2); 4-iodopyrazolate (3); PPh3 = triphenylphosphine} were synthesized and characterized by elemental analyses, infrared ...
