A simple method for the preparation and selective functionalization of 4,5-diaminopyrazoles

A simple procedure for the synthesis and further functionalization of 4,5-diaminopyrazoles using mild conditions is reported herein. The desired products were obtained in good yield, and the structures have been confirmed by X-ray crystallography. A simple procedure for the synthesis and further fun...
