羟基芳族化合物用作安全剂的用途
摘要：
式(I)化合物或其盐作为作物或有用植物的安全剂以对抗农业化学品对这些植物的植物毒性作用，优选作为安全剂对抗农药如除草剂对这些植物的植物毒性作用，其中R1为羧基或羧基衍生物，优选为下式基团：-CN、-C(＝X)-Y-R或-C(＝X)-Het，其中X为O、S或NRa或N-NRaRb，Y为O、S、NRc或NRc-NRdRe，R为H、(经取代的)烃基(KW)或酰基，和其中每个基团Ra、Rb、Rc、Rd和Re是如R所定义的基团，或为式-OR*基团，其中R*为如R所定义的基团，R2为H、(经取代的)KW或杂环基，或，若Z＝O或S，则也为酰基，(R3)n为n个R3基团，其如权利要求1中所定义，Z为式O或S(O)x基团，其中x＝0、1或2，和n为0、1、2、3或4的整数。
摘要（英）：

The invention relates to compounds of the formula (I) or salts as safeners for crop plants or useful plants against phytotoxic actions of agrochemicals, preferably as safeners against the action of pesticides, such as herbicides, in these plants, wherein R<1> is carboxyl or a derivative of a carboxyl group, preferably a radical of the formula -CN, -C(=X)-Y-R or -C(=X)-Het, in which X is O, S or NR or N-NRR, Y is O, S, NR or NR-NRR, R is H, a (substituted) hydrocarbon radical (KW) or acyl, where each of the radicals R, R, R, R and R is as defined for R or a radical of the formula -OR<*>, where R<*> is as defined for R, R<2 >is H or (substituted) KW or a heterocyclic radical, or, if Z=O or S, also an acyl radical, (R<3>)n are n radicals R<3>, as defined in claim 1, Z is a group of the formula O or S(O)x, where x=0, 1 or 2, and n is an integer of 0, 1, 2, 3 or 4.
