The Synthesis and Insecticidal Activity of a Series of 2‐Aryl‐1,2,3‐triazoles

Two synthetic routes to 2-aryl-1,2,3-triazoles are outlined. These have been used to synthesise a wide range of compounds of this structural type. Their insecticidal activities were evaluated against a number of veterinary and public health pests. The activity of these compounds is especially good against the housefly (Musca domestica). Structure–activity relationships are discussed particularly in relation to the physical properties of the compounds.
