Abstract

The synthesis and unequivocal characterization of all six isomers of benzoyl phenyl 1-methylpyrazole (2) are described. The isomer of 2 isolated as one of the products of the reaction of 1,1-dimethyl-1-phenacylhydrazinium bromide (1) with base was shown to be the only previously reported isomer, 5-benzoyl-3-phenyl-1-methylpyrazole (2b).
