The intermediate compounds may undergo a single cyclization to the desired pyrazoles, or once the pyrazoles are formed this compound can undergo a second cyclization to a new fused-ring system, pyrazoloimidazolediones.
This is the case, in particular, of insecticides for the protection of various crops, particularly in view of the combination of Bayer and ACS's portfolio of products in two very successful new classes of chemical substances, neonicotinoids, where Bayer controls the main products, and pyrazoles, which are unique to ACS.
Also, pyrazoles and isozazoles [6] have been the subject of chemical and biological studies due to their interesting pharmacology including antipyretic, analgesic, antiinflammatory potential herbicidal, fungicidal and leishmanicidal [7-10] properties.
He has assembled information for coordination chemists from over 1,300 papers covering 1999 to 2007 in a style that largely follows the original but expands to include recent studies on scorpionate ligands that feature heterocycles other than pyrazoles.
