Claims
- 1. A 2-phenoxypyrimidine derivative having the formula (I): ##STR56## wherein X is a halogen atom; R.sup.1 is a hydrogen atom or --(CH.sub.2).sub.m R.sup.3, wherein R.sup.3 is a cyano group, a formyl group, a lower dialkylamino group, a phenyl group, a pyridyl group, a trimethylsilyl group, a naphthyl group, a lower alkoxycarbonyl group, a benzoyl group, a lower alkylthio group, a phenylthio group, a lower alkylsulfonyl group or a benzyloxy group; and m is 1, 2 or 3, or a group of the formula: ##STR57## wherein R.sup.4 is a hydrogen atom or a lower alkyl group; R.sup.5 is a lower alkyl group or a group of the formula: ##STR58## wherein X.sup.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.sup.5 is an alkyl group, n is 1; and R.sup.2 is a chlorine atom or a methoxy group; and when R.sup.1 is a group of the formula: ##STR59## X is a chlorine atom at the 6-position and R.sup.2 is a methoxy group; and when R.sup.1 is --(CH.sub.2).sub.m R.sup.3, X is a halogen atom at the 6-position.
- 2. The 2-phenoxypyrimidine derivative according to claim 1, which has the formula (III): ##STR60## wherein R.sup.3 is a cyano group, a formyl group, a lower dialkylamino group, a phenyl group, a pyridyl group, a trimethylsilyl group, a naphthyl group, a lower alkoxycarbonyl group, a benzoyl group, a lower alkylthio group, a phenylthio group, a lower alkylsulfonyl group or a benzyloxy group; R.sup.2 is a chlorine atom or a methoxy group; X.sup.3 is a halogen atom; and m is 1 or 2.
- 3. The 2-phenoxypyrimidine derivative according to claim 1, which has the formula: ##STR61## wherein R.sup.4 is a hydrogen atom or a lower alkyl group; R.sup.5 is a lower alkyl group or a group of the formula: ##STR62## wherein X.sup.2 is a halogen atom, a lower alkyl group, a lower alkoxy group or a nitro group; and n is 0 or 1, provided that when R.sup.5 is an alkyl group, n is 1.
- 4. The compound according to claim 1, wherein R.sup.1 is a methoxy group.
- 5. The compound according to claim 1, wherein R.sup.2 is a methoxy group; and R.sup.3 is a benzoyl group, a benzyloxy group, a lower alkylthio group, a lower alkoxycarbonyl group, a phenylthio group, a lower alkylsulfonyl group or a cyano group.
- 6. The compound according to claim 1, wherein R.sup.2 is a methoxy group; and R.sup.3 is a benzoyloxy group, a lower alkylthio group, a phenylthio group or a lower alkylsulfonyl group; and m is 1.
- 7. The compound according to claim 1, wherein n is 0 and R.sup.5 is a group of the formula: ##STR63##
- 8. The compound according to claim 1, wherein n is 0 and R.sup.5 is a group of the formula: ##STR64## wherein X.sup.4 is a hydrogen atom, a methyl group, a methoxy group or a nitro group.
- 9. A herbicidal composition, which comprises a herbicidally effective amount of a 2-phenoxypyrimidine derivative of the formula (I) as defined in claim 1, and an agricultural adjuvant.
