Iodobenzene diacetate mediated oxidation of N-substituted hydrazones of chalcones: An efficient regioselective synthesis of 1,3,5-trisubstituted pyrazoles

Article abstract of DOI:10.1080/00397910802640038

Iodobenzene diacetate, a relatively benign nonmetallic oxidant, has been utilized efficiently for the oxidation of N-substituted hydrazones of chalcones to afford 1,3,5-trisubstituted pyrazoles under mild reaction conditions.
