Abstract
The mass spectra of a number of syn- and anti-1-phenylpyrazol-4-yl oximes have been studied. syn- and anti-Paris where available gave identical mass spectra; although no Beckmann rearrangement occurred, a transfer of the oximino-hydrogen to the pyrazole nucleus with concommittant fission of the side chain was shown to take place.Keywords
