摘要:
Herbicidally active substituted phenylsulfonyl urea derivatives of the formula ##STR1## in which X is phenyl or phenoxy,R is ##STR2## and R.sup.1 and R.sup.2 each independently is methyl or methoxy.They are made from phenylisocyanates of the formula--SO.sub.2 --N.dbd.C.dbd.Owhich are produced by reacting a phenylsulfonamide of the formula ##STR3## with phosgene or with trichloromethyl chloroformate in the presence of an aliphatic isocyanate.

摘要:
Substituted phenylsulfonylurea-derivatives of the general formula ##STR1## wherein X represents an oxygen atom or a direct bond, Y and Z each represents a halogen atom, a lower alkyl group, a lower alkoxy group or a nitro group, R represents a group: ##STR2## wherein R.sup.1 and R.sup.2 each represents a lower alkyl group or a lower alkoxy group, m and n each represents 0, 1 or 2 with the proviso that m and n do not represent 0 at the same time, are novel and find use as herbicides. Corresponding substituted benzenesulfonyl isocyanates are novel intermediate compounds for use in preparing compounds of formula (I).
