Abstract: Depending on the reaction conditions, two alternative cyclizations are possible for [3 + 3] cyclocondensation of pyrazolone derivative 1a and ethyl cyanoacetate of type pyrano [2,3-c] pyrazol-6(1H)-one 2 and pyrano [2,3-c] pyrazol-4(1H)-one 3. Keeping of enaminic system… read more here.

Abstract: Abstract A Cu(II) complex based on a pyrazolone derivative, 2-hydroxy-N′-((1-(4-methoxyphenyl)-3methyl-5-oxo-4,5-dihydro-1H-pyrazol-4-yl)(phenyl)methylene)benzohydrazide (H2L), has been prepared. IR spectra, UV-vis spectra, elemental analysis and single-crystal X-ray diffraction indicate that the Cu(II) complex was mononuclear with the chemical composition… read more here.
