The synthetic routes to three differently connected bipyrazole systems,
namely; 1,1`-, 1,3`- and 1,4`-bipyrazoles were reported. The main synthetic platforms
were cyclocondensation reactions. Many of the reported bipyrazole derivatives had
potent applications in material science as well as in pharmaceutical fields.
