摘要:
A phenoxypyridine derivative having the formula(CH.sub.3 COO).sub.n CH.sub.3-n R (I)wherein R represents ##STR1## and n is 1 or 2 is produced by reacting a phenoxypyridine-N-oxide derivative having the formula(CH.sub.3 COO).sub.n-1 CH.sub.4-n R' (III)wherein R' represents ##STR2## and n is 1 or 2 with acetic anhydride. The phenoxypyridine derivatives are especially suitable for producing synthetic pyrethroids having excellent insecticidal and acaricidal activity in high yield and an economical process.
