VERFAHREN ZUR HERSTELLUNG VON MORPHOLINO-DITHIOTHIAZOLEN
1. A process for the production of morpholino-dithiothiazoles of the general formula (I) : see diagramm : EP0001098,P7,F1 in which R represents a 2-benzthiazole or 2-naphthiazole radical which may optionally be substituted by straight-chain or branched-chain alkyl groups containing from 1 to 10 carb...

Zusammenfassung: | 1. A process for the production of morpholino-dithiothiazoles of the general formula (I) : see diagramm : EP0001098,P7,F1 in which R represents a 2-benzthiazole or 2-naphthiazole radical which may optionally be substituted by straight-chain or branched-chain alkyl groups containing from 1 to 10 carbon atoms, by reacting compounds of the general formula (II) (R-S-)n M in which R has the meaning indicated above, M represents a metal ion of sodium, potassium, lithium, magnesium, calcium, boron or aluminium and n denotes an integer from 1 to 3, with morpholine, sulphur and an oxidising agent in the presence of a catalyst in a predominantly aqueous medium, characterised in that an aqueous solution of a mercaptothiazole salt of the above general formula (II) is used and acid is added to the mixture during the course of the reaction. |
