NEW MATERIAL:A nitroimino derivative shown by the formula I (R is H or alkyl; X is halogen, alkyl, alkoxy, alkylthio, nitro, cyano, amino, acylamino, dialkylamino, alkoxycarbonyl, acyl, alkylsulfonyl, alkylsulfinyl, haloalkyl, haloalkoxy, haloalkylthio, formly, alkenyl, alkynyl, or haloalkenyl; l is 0-4; m is 2-4). EXAMPLE:1-(2-Chloro-5-pyridylmethyl)-2-(nitroimino)tetrahydropyrimidine. USE:Useful as an insecticide showing perfectly controlling action with a small amount of it. PREPARATION:For example, a compound shown by the formula II (e.g., 2- nitroiminoimidazolidine) is reacted with a compound shown by the formula III (Hal is halogen) to give a compound shown by the formula I. |
