This invention relates to a process for the production of benzothiazolyl sulphenamides corresponding to the following general formula: ##STR1## in which a corresponding 2-mercaptobenzothiazole or a dibenzothiazolyl-2,2'-disulphide is reacted with a primary or secondary amine at temperatures of from 0 to 100.degree. C. in the presence of ammonia, oxygen, a copper-containing catalyst and a reaction medium containing an excess of the primary or secondary amine or of a mixture of that amine with water and/or a water-miscible organic solvent.
