    Abstract: Hydroxylamine derivatives have the general formula I Aryl-A-O-B I where Aryl is an unsubstituted or substituted, mononuclear or binuclear, isocyclic radical; A is a 1,4-butenylene group of the general formulae IIa or IIb IIa IIb where R1, R2, R3, R4 and R5 are each hydrogen, halogen, C1-C6-alkyl or C1-C6-alkenyl; B is NH2 or a dicarboximide group of the general formula III III where Z is unsubstituted or substituted phenylene, naphthylene, pyridinylene, cyclopentylene, cyclohexylene, cyclohexenylene, C2-C4-alkenylene or C2-C4-alkylene. The dicarboximides are intermediates for the compounds wherein B is NH2. The latter are used in synthesizing herbicidal compounds.

    Abstract: The invention relates to a method for producing a solution of tanning agents containing sulphone. In said method, a) a component A is produced as follows: a1) phenol is reacted with concentrated sulphuric acid or with oleum with an SO3 content of between 20 and 65 wt. %, or with a mixture of sulphuric acid and oleum with an SO3 content of between 20 and 65 wt. %, whereby the molar ratio of total sulphuric acid, calculated in the form of SO3 to phenol is between 0.7: 1 and 1.5: 1, at a temperature of between 100 and 180 DEG C to obtain a mixture containing phenolsulphonic acid, dihydroxydiphenyl sulphone and sulphuric acid, or the individual components are blended to produce a corresponding mixture; a2) said mixture is subsequently condensed at between 40 and 90 DEG C per mol of phenol units present with between 0.25 and 4 mol of urea and between 0.5 and 4 mol of an aliphatic aldehyde comprising between 1 and 6 C atoms, a3) optionally a pH value of between 4 and 5 is set by adding a base; b) a component B is produced as follows: b1) dihydroxydiphenyl sulphone is reacted with between 0.5 and 5 mol of an aliphatic aldehyde comprising between 1 and 6 C atoms and between 0.4 and 2 mol of sodium sulphite per mol of dihydroxydiphenyl sulphone, at a temperature of between 90 and 180 DEG C; b2) optionally a pH value of between 3.5 and 5.5 is set by adding an acid. c) Between 10 and 90 wt. % of component A is mixed with between 90 and 10 wt. % of component B, (the sum of A and B amounting to 100 wt. %) and if not already accomplished in steps a3) and b2), the pH value of the mixture is set at between 3.5 and 5.5.

    Abstract: A process is disclosed for controlling undesirable plant growth and for regulating plant growth, by applying to the plants derivatives of azaanthraquinones and/or azaxanthones having formula (I), in which X, Y, Z and the residues R to R have the following meanings: R is hydrogen, methyl; R -R are (a) hydrogen, (b) halogen, (c) nitro, (d) COOR , in which R stands for C1-C4-alkyl, (e) CONH2 and CONR R , in which R and R stand for C1-C4-alkyl, (f) C1-C8-alkyl, which may bear one to three of the following substituents: halogen, hydroxy, C1-C6-alkoxy, (g) C3-C6-alkenyl, (h) C1-C4-alkoxy, (i) hydroxy, (j) amino or NR R , (k) phenyl, which may bear one to five halogen atoms or one to three of the following substituents: nitro, C1-C4-alkoxy, C1-C4-alkyl or C1-C4alkyl halide; X, Y are N, N -O or CH, with the proviso that only a nitrogen atom or a N-oxide group be contained in the ring; Z is oxygen, sulphur or a C = O group; A is oxygen or sulphur. Also disclosed are new azaanthraquinones and azaxanthones and herbicidal and bioregulatory agents containing the same.
