Synthesis and Insecticidal Activity of Some New 3‐[4(3H)‐Quinazolinone‐2‐(yl)thiomethyl]‐1,2,4‐ triazole‐5‐thiols

Abstract

A series of 14 new 3-[4(3H)-quinazolinone-2-yl)thiomethyl]-1,2,4-triazoles were prepared and characterized by elemental analyses, IR, [ 1 H] NMR and mass spectral data. Four of the compounds showed insecticidal activity equivalent to that of malathion against the adult stage of the blow fly (Chrysomyia albiceps). However, their activity against the larval stages of this insect species was considerably weaker.
