摘要:
A tetrahydrofuran derivative represented by the general formula ##STR1## wherein X.sub.1 and X.sub.3 represent a hydrogen or halogen atom, and X.sub.2 represents a halogen atom or a trifluoromethyl group. The compounds have excellent herbicidal activity and can be prepared by reacting a compound of the formula ##STR2## wherein R represents a nitro group or a group of the formula ##STR3## in which X.sub.1, X.sub.2 and X.sub.3 are as defined above, with 3-hydroxytetrahydrofuran in the presence of an alkali.
摘要:
Nitrodiphenyl ether derivatives of the general formula: ##STR1## wherein X represents chlorine, fluorine, methyl or trifluoromethyl and n is an integer of 1-3 are valuable as herbicides, the compounds and compositions containing these compounds possessing an excellent herbicidal activity to a wide variety of undesirable weeds with an extremely low toxicity to useful crops.
