摘要:
The invention relates to a process for the preparation of halogenoindenonecarboxylic acids of the formula ##STR1## in which R.sup.3 is preferably chlorine and R, R.sup.1 and R.sup.2 are, for example, H or -CH.sub.3. If these acids are novel, the corresponding substances are claimed. The invention also relates to corresponding esters of these acids, which contain reactive end groups. The compounds are suitable for the preparation of light-sensitive polymers.
摘要:
Herbicidal .alpha.-(4-substituted) phenoxypropionylazoles of the formula ##STR1## wherein Z is the 4-trifluoromethylphenyl, 3,5-dichloropyrid-(2)-yl or 3-chloro-5-trifluoromethyl-pyrid-(2)-yl radical, and A is an azole radical which may or may not be substituted and is bonded through a ring nitrogen atom, such as pyrazole, imidazole, triazole or tetrazole, are useful for selectively controlling monocotyledonous weeds. Preferably, the cultivated plants are dicotyledonous, such as wheat, cotton, sugar beet, soybeans and vegetables.
摘要:
The novel .alpha.-phenoxy-propionic acid-.gamma.-butyrolactone esters and thioesters of the formula ##STR1## wherein X is oxygen or sulfur, andZ is the 4-trifluoromethylphenyl group or the 3,5-dichloropyridyl-2-oxy group,have a herbicidal action. They are particularly suitable for selectively controlling gramineous weeds in cultivated crops.
摘要:
The present invention concerns new .alpha.-phenoxy-thiolpropionic acids and salts of the formula ##STR1## wherein R is hydrogen a metal cation or the cation of an amino- or ammonio-group, Z is a substituted phenyl or a substituted pyrid-2-yl radical.These compounds have herbicidal activity by themselves but can be used as intermediats for the synthesis of more active derivatives.
摘要:
The present invention concerns new pyridyloxy-phenoxy-alkanecarboxylic acid derivatives of the formula ##STR1## wherein A is hydrogen, halogen, alkyl, alkoxy, cyano, nitro or carbothiamideB is hydrogen, halogen, alkyl, cyano, mono- or dialkylamino, alkoxy-carbonyl or carbothiamideC is hydrogen, halogen, cyano, nitro or carbothiamideD is hydrogen, halogen, alkyl, mono- or dialkylaminoR.sub.1 is hydrogen, alkyl, alkoxyalkyl or benzyl R is the rest of the acid a salt or an ester,With the proviso that if the pyridine ring is substituted by halogen and/or alkyl and C is also halogen, then the radicals A, B and D must contain no less than two halogen atoms or alkyl radicals.These derivatives have herbicidal and plant-growth regulating activity.
