Synthesis and Insecticidal Evaluation of N-tert-Butyl-N′-thio[1-(6-chloro-3-pyridylmethyl)-2-nitroiminoimidazolidine]-N,N′-diacylhydrazines

A series of novel N-tert-butyl-N′-thio[1-(6-chloro-3-pyridylmethyl)-2-nitroiminoimidazolidine]-N,N′-diacylhydrazines were synthesized by the reaction of chlorosulfenyl(N-tert-butyl-N,N′-diacylhydrazines) with 1-(6-chloro-3-pyridylmethyl)-2-nitroiminoimidazolidine (imidacloprid) in the presence of sodium hydride. Their larvicidal activities were evaluated. All of them exhibited insecticidal activities against Oriental armyworm and bean aphids....
