Literature References
The combination with Chromium(VI) oxide, 12522 is a valuable reagent for oxidation of primary and secondary alcohols to carbonyl compounds in very high yields: Tetrahedron Lett., 4499 (1973). With Pyridinium chlorochromate, A11752, allylic alcohols are oxidized selectively in the presence of secondary alcohols: J. Org. Chem., 48, 4766 (1983). Reaction of pyrazoles with malonic esters gives a family of cross-conjugated monomeric betaines: Synthesis, 629 (1989):
Applications
3,5-Dimethyl-1H-pyrazole is combined with Chromium(VI)Â oxide, is a valuable reagent for oxidation of primary and secondary alcohols to carbonyl compounds. It reacts with malonic esters gives a family of cross-conjugated monomeric betaines. It is a common reagent for the preparation of pyrazolato ligated complexes. It is also used to prepare N-1-substituted derivatives having antibacterial activity.
