摘要

Pyridine compounds of the following general formula; use of the same as arthropod controllers; and intermediates for the preparation thereof: wherein R?1 and R2¿ are each independently halogeno or C¿1-4? haloalkyl; n and m are each independently an integer of 1 to 3; and R?3¿ is hydrogen, NR4R5 (wherein R?4 and R5¿ are each independently hydrogen, C¿1-4? alkyl, or the like), or N=CR?7R8¿ (wherein R7 is hydrogen or C¿1-4? alkyl, and R?8¿ is C¿1-4? alkoxy or optionally substituted phenyl).
