Structures of 1-Phenyl-3-methyl-pyrazolone-5- and its Benzoyl Derivatives
Okafor, Emmanuel Chukwuemeka
, p. 1019 - 1023 (2007/10/02)
The sturctures of 1-phenyl-3-methyl-pyrazolone-5 and its benzoyl derivatives have been investigated by means of IR, UV, NMR, and mass spectral spectroscopy. 1-Phenyl-3-methyl-pyrazolone-5-is found to exist as a zwitter ion in the solid state, in the 5-ket
