Abstract
The present invention relates to a novel method for preparing bis(3-aminophenyl) disulphides of the general formula (I) and 3-aminothiols of the general formula (II), where X,Y have the meanings stated in the description, which serve as intermediates for the preparation of phenyl sulphoxides having insecticidal, acaricidal and nematicidal activity.
Claims6
A bis(3-nitrophenyl) disulphide of the formula (IV)
- in which the residues X and Y are each independently methyl, ethyl, methoxy, ethoxy, or fluorine.
A bis(3-aminophenyl) disulphide of the formula (I)
- in which the residues X and Y are each independently methyl, ethyl, methoxy, ethoxy or fluorine.
A bis(3-aminophenyl) disulphide of the formula (I)
- which is 3,3′-disulphanediylbis(4,6-dichloroaniline).
A 3-Aminothiol of the formula (II)
