Synthesis and Insecticidal Activity of Tetrazole‐Linked Triazole Derivatives

A new series of 4‐(4‐substitutedbenzylideneamino)‐5‐((1‐methyl‐1H‐tetrazol‐5‐ylthio)methyl)‐4H‐1,2,4‐triazole‐3‐thiol derivatives ( 5a , 5b , 5c , 5d , 5e , 5f , 5g , 5h , 5i , 5j , 5k ) are prepared using 4‐amino‐5‐((1‐methyl‐1H‐tetrazol‐5‐ylthio)methyl‐4H‐1,2,4‐triazole‐3‐thiol ( 4 ), as an intermediate compound. The structures of all the newly synthesized products are established supported by their spectral ¹H NMR, ¹³C NMR, FTIR, electrospray ionization mass spectrometry (mass), and analytical data. All the compounds are screened for their insecticidal activity against Plodia interpunctella, and six compounds exhibited significant activity.
