A scalable approach to diaminopyrazoles using flow chemistry

This Letter reports on how the combination of microwave and continuous flow chemistry facilitated the convenient preparation of aminopyrazoles from commercial aryl halides. The method was applied to a variety of substrates with good to excellent yields an

The Reaction of Phenylmalononitrile with Hydrazine. Synthesis and Properties of 3,5-Diamino-4-phenylpyrazole, 2-Amino-3-phenylpyrazolopyrimidine, and Related Compounds

3,5-Diamino-4-phenylpyrazole was prepared by the reaction of phenylmalononitrile with hydrazine hydrate.This hitherto unknown polyfunctional heterocycle reacted with acetylacetone, ethyl acetoacetate, 5-oxobutyraldehyde, malonaldehyde, diethyl (ethoxymeth
