Abstract
Abstract: b-Tosylhydrazono phosphonates are novel, bifunctional reagents which were used for a concise approach to a wide range of polysubstituted pyrazoles in a single operation from aromatic and aliphatic aldehydes. Key words: b-tosylhydrazono phosphonate, aldehyde, a, b-unsaturated tosylhydrazone, pyrazole
