Synthesis of pyrazoles and condensed pyrazoles

Journal of Heterocyclic Chemistry, 1999
AbstractThis review introduces the synthesis of various pyrazoles reported by us and some other research groups during 1989–1998. Some of papers in this review deal with the development of potent pyrazoles or with the synthesis of potential pyrazoles aiming at agrochemicals and/or drugs.

Pyrazoles. III. PMR studies of pyrazoles

Recueil des Travaux Chimiques des Pays-Bas, 1967
AbstractSubstituents with electron withdrawing capacities are found to induce a paramagnetic displacement of the chemical shifts of protons and methyl groups in the remaining positions of the pyrazole ring. For the 4‐position this effect is considered to be due primarily to resonance interaction of substituent and pyrazole ring.
