Novel N-cyanoguanidyl derivatives: Synthesis and studying their toxicological activity against Spodoptera littoralis and Schizaphis graminum

Abstract

Reaction of N-cyanoguanidine with acid chlorides and aroylisothiocyanates gave the respective; N-(N-cyanocarbamimidoyl)aryl-2-carboxamides 1-5 and N-[(N-cyanocarbamimidoyl)carbamothioyl]benzamides 6-10, which have a Neonictinoid insecticide’s active group moiety (=N–CN). They have more toxicological activity against wheat Aphid (Schizaphis graminum) than Spodoptera littoralis.
