Chemistry of Bipyrazoles: Synthesis and Applications covers the synthetic pathways for all types of bipyrazoles. 5 chapters cover bipyrazole systems, N, N- and N, C-bipyrazoles, namely 1,1`-bipyrazole, 1,3`-bipyrazole, 1,4`-bipyrazole, 3,3`-bipyrazoles, 3,4`-bipyrazoles and 4,4`-bipyrazoles The contents explain several types of reactions: 1) condensation reactions of hydrazines with tetracarbonyls, dihydroxydicarbonyl compounds or pyrazole-based difunctional compounds; 2) 1,3-dipolar cycloaddition of pyrazole-based hydrazonoyl halides with activated methylene compounds; 3) metal catalyzed cross-coupling reactions.>The book contents are presented in an easy-to-understand manner suitable for readers in organic chemistry at senior levels of education and industry expertise. Each chapter is supplemented with detailed references.
