Phenylsulfonylureas, processes for their preparation, and their use as herbicides and plant growth regulators
摘要：
Compounds of the formula (I) and their salts as defined in claim 1, ##STR1## in which R.sup.1 is CO--Q--R.sup.8, where R.sup.8 =H or RR.sup.2 and R.sup.3 are H or (C.sub.1 -C.sub.4)alkyl,R.sup.4 is H, R, RO, OH, RCO, RSO.sub.2, PhSO.sub.2R.sup.5 is RSO.sub.2, PhSO.sub.2, PhCO, RNHSO.sub.2, R.sub.2 NSO.sub.2, RCO, CHO, COCOR', CW--T--R.sup.9, CW--NR.sup.10 R.sup.11, CW--N(R.sup.12).sub.2 orR.sup.4 and R.sup.5 together are the chain (CH.sub.2).sub.m B or --B.sup.1 --(CH.sub.2).sub.m1 B-- where B=SO.sub.2, CO; m=3, 4; m.sup.1 =2, 3;T and W=O, S; Q=O, S, NR.sup.13 where R.sup.13 =H, R;R.sup.6 =H, R, RO, RCO, ROCO, Hal, NO.sub.2, CN;R.sup.7 =H, CH.sub.3 ; R.sup.9 =R; R.sup.10, R.sup.11 =H, R; N(R.sup.12).sub.2 =heterocycleA=pyrimidinyl and triazinyl radical or an analog thereof,where R=(substituted) aliphatic hydrocarbon radical, are suitable as selective herbicides. They are prepared by analogous processes via sulfonamides, some of which are new, of the formula (II).
摘要（中）：

其中R 1是CO-Q-R 8，其中R 8 = H或R R 2和R 3是H或（C 1 -C 4）烷基，R 4是H，R ，ROO，OH，RCO，RSO2，PhSO2 R5是RSO2，PhSO2，PhCO，RNHSO2，R2NSO2，RCO，CHO，COCOR'，CW-T-R9，CW-NR10R11，CW-N（R12）2或R4和R5 链（CH2）mB或-B1-（CH2）m1B-，其中B = SO2，CO; m = 3,4; m1 = 2，3; T和W = O，S; Q = O，S，NR 13，其中R 13 = H，R; R6 = H，R，RO，RCO，ROCO，Hal，NO2，CN; R7 = H，CH3; R9 = R; R10，R11 = H，R; N（R 12）2 =杂环A =嘧啶基和三嗪基或其类似物，其中R =（取代的）脂族烃基适合作为选择性除草剂。 它们通过类似的方法通过磺酰胺（其中一些是新的）式（II）制备。
