Synthesis and insecticidal activities of novel pyrazole oxime ether derivatives with different substituted pyridyl rings

Abstract

Structure-activity relationships were also examined. Results suggested that the tert-butoxycarbonyl group, as well as the position between tert-butoxycarbonyl and the atom N of the pyridyl ring, were essential to obtaining the acarcidal activity of the title compounds.
