Abstract

Abstract 1-Alkyl-1 H-pyrazole-4-carbaldehyde oximes reacted with acetic anhydride to give the corresponding nitriles, which is typical for anti isomers of aldoximes. The anti configuration of 5-methyl-1-propyl-1 H-pyrazole-4-carbaldehyde oxime in crystal was unambiguously determined by X-ray analysis.
