NEW MATERIAL:A compound shown by the formula I [n is 0 or 1; R and R<1>-R<6> are H or alkyl and R<3> and R<4> are further OH; X is S, O, NR<7> (R<7> is H, halogen, OH, alkoxy, alkyl, etc.,) or CH-R<8> (R<8> is H, alkyl, aryl, etc.,); Y is N or CR<9> (R<9> is H, halogen, OH, alkyl, phenyl, etc.,); Z is 5-6-membered heterocyclic group (which may be replaced with halogen, alkyl, NO2, CN, etc.,) containing at least one of O, S, and N]. EXAMPLE:1-(2-Chloro-5-pyridylmethyl)-2-(nitromethylene)pyrrolidine shown by the formula II. USE:An insecticide showing a remarkable controlling effect on insect pests having resistance to organic phosphorous insecticides and carbamate insecticides. PREPARATION:For example, a compound shown by the formula III [X is S, O or NR<10> (R<10> is R<7> is except R<7>)] is reacted with a compound shown by the formula IV (R' is alkyl or benzyl), to give a corresponding compound shown by the formula I (Y is CR<9>). |
