Advances in Synthesis of Pyrazole and Pyrazole Derivatives

The main methods of synthesis of pyrazole and pyrazole derivatives were reviewed in this paper.The former included the reactions of 1,3-diketone compounds and hydrazine,the reactions of alkyl diazo-compounds and alkenoene compounds,the reactions of ethyl acetoacetate and hydrazine,the reactions of acrylonitrile or malononitrile compounds and hydrazine,the reactions of alkenone compounds and hydrazine.The synthetic technologies included solid-synthesis and micro wave-assistant synthesis.
