摘要:
A compound represented by the following formula ##STR1## wherein X.sup.1 and X.sup.2 are identical or different and each represents a hydrogen atom, a lower alkyl group, a lower alkoxy group, a halogen atom, a trifluoromethyl group or a trifluoromethoxy group;Y.sup.1 and Y.sup.2 are identical or different and each represents a hydrogen atom, a lower alkyl group, a lower alkoxy group, a lower alkylthio group, a cyano group, a nitro group, a halogen atom or a trifluoromethyl group;Z represents an oxygen or sulfur atom; andn is 0 or 1;excepting the case where n is 0 and X.sup.1 and X.sup.2 are both hydrogen atoms, the case where n is 1 and X.sup.1 and X.sup.2 are members selected from the class consisting of hydrogen and halogen (excepting iodine) atoms, and the case where Y.sup.1 and Y.sup.2 are membrs selected from the class consisting of hydrogen and halogen (excepting iodine) atoms and nitro groups. This compound is useful as an insecticidal and acaricidal (miticidal) agent.
摘要:
A compound of the formula ##STR1## wherein Y represents a halogen atom, a lower alkyl group, a lower alkoxy group or a trifluoromethyl group and R represents a lower alkyl group. This compound can be produced by reacting a compound of the formula ##STR2## or a reactive derivative thereof with an aniline derivative of the formula ##STR3## and is useful as a herbicide.
摘要:
A compound of the general formula ##STR1## wherein X.sub.1 represents a hydrogen, fluorine, chlorine or bromine atom, X.sub.2 represents a fluorine, chlorine or bromine atom, R represents a hydrogen atom or a lower alkyl group, and Y represents a fluorine, chlorine or bromine atom, or a trifluoromethyl or cyano group.This compound is prepared by reacting a compound of the formula ##STR2## or a reactive derivative thereof with a compound of the formula ##STR3## and is useful as an insecticide.
摘要:
A herbicidal composition containing as an active ingredient a compound of the formula ##STR1## wherein R.sub.0 represents a hydrogen atom or a lower alkyl group, and R.sub.1, R.sub.2 and R.sub.3 each represent a hydrogen or halogen atom, or a lower alkyl, lower alkoxy or lower alkenyloxy group, which is especially useful for application to aquatic rice paddies, and novel compounds of formula (I) wherein R.sub.0, R.sub.1, R.sub.2 and R.sub.3 have the same meanings as defined above, provided that R.sub.1, R.sub.2 and R.sub.3 do not represent hydrogen atom at the same time.
