PYRAZOLE DERIVATIVES AND PROCESS FOR PRODUCING THE SAME, AND PESTICIDES CONTAINING THE SAME AS THE ACTIVE INGREDIENT

摘要

Novel pesticides having a high penetration/migration activity and a high safety with little effect on the application environment. Novel 1-aryl-3-cyano-5-heteroarylalkylaminopyrazole derivatives represented by general formula (1), A: formulae (A-1), (A-2), (A-3), (A-4) wherein X represents N or C-halogeno; R<1> represents alkyl, alkenyl, alkynyl or haloalkyl; R<2> represents hydrogen, alkyl or acyl; R<3> represents hydrogen or alkyl; A represents one of the groups represented above by A-1 to A-4; R<4> represents hydrogen, alkyl or halogeno; and n is 0, 1 or 2, provided that R<1> is haloalkyl (other than perhaloalkyl) when A is A-1 and n is 0, and that n is not 0 when A is A-4.
