Crystal and molecular structure of a 4 oximino 5 imino pyrazoline active ester

Article abstract of DOI:10.1111/j.1399-3011.1975.tb02425.x

The crystal structure of an active 4 oximino 5 imino pyrazoline ester has been determined by single crystal X ray diffraction methods. The possible reasons for its high reactivity toward nucleophilic reagents are briefly discussed.
