Reaction Schemes

The reactions of several substituted 5-chloropyrazoles with hydrazine hydrate and guanidine, respectively, were investigated in ethanol and dimethyl formamide media. In certain cases, only SN2 reactions occurred, while in others the 5-hydrazino- and 5-guanidopyrazoles reacted still further to yield related compounds with two pyrazole rings. On the basis of the intermediates and the different condensation products isolated, reaction schemes are proposed for the reactions discussed.
