2-phenoxypyrimidine derivative and herbicidal composition

Abstract

Abstract A 2-phenoxypyrimidine derivative having the formula: ##STR1## wherein X is a halogen atom or ##STR2## wherein X 1 is a halogen atom, a lower alkyl group or a lower alkoxy group and k is 0, 1 or 2; R 1 is a hydrogen atom, a benzyl group, --(CH 2 ) m R 3 wherein R 3 is a cyano group, a formyl group, a dialkylamino group, a phenyl group, a pyridyl group, a trimethylsilyl group, a naphthyl group, an alkoxycarbonyl group, a benzoyl group, an alkylthio group, a phenylthio group, an alkylsulfonyl group or a benzyloxy group and m is 1, 2 or 3, or ##STR3## wherein R 4 is a hydrogen atom or a lower alkyl group, R 5 is a lower alkyl group or ##STR4## wherein X 2 is a hydrogen atom, a halogen atom, a lower alkyl group, a lower alkoxy group or a nitro group, n is 0 or 1, provided that when R 5 is an alkyl group, n is 1; and R 2 is a chlorine atom or a methoxy group, provided that when R 1 is a hydrogen atom or a benzyl group, X is ##STR5## and R 2 is a methoxy group, when R 1 is ##STR6## X is a chlorine atom at the 6-position and R 2 is a methoxy group, and when R 1 is --(CH 2 ) m R 3 , X is a halogen atom at the 6-position.
