Process for the preparation of 2-aminodithiothiazoles and 2-aminotrithiothiazoles

2-(aminodithio)thiazoles and 2-(aminotrithio)thiazoles are prepared by reacting a mixture of a 2-mercaptothiazole or a dithiazolyl 2,2'-disulphide with a saturated secondary heterocyclic amine and sulphur in a reaction medium containing an inert organic solvent in the presence of an oxidant. The reaction is carried out in the present of ammonia and a catalyst containing copper, a copper compound or a cerium compound, and the oxidant is molecular oxygen or a gas containing oxygen. In particular, 2-(4-morpholinodithio)benzo-thiazole, which is technically interesting as a vulcanization accelerator, can be prepared in high product yield and virtually without by-products using the oxidant which is less expensive and can be handled with greater ease.

Process of preparing an amino thiazolyl disulfide using a water soluble salt in combination with wet 2,2-dithiobis(benzothiazole)

In a known process for preparing 2-(4-morpholinodithio)-benzothiazole using 2,2'-dithiobis(benzothiazole) along with morpholine, sulfur, an inert organic solvent such as isopropyl alcohol and an oxidizing agent, the improvement wherein a water soluble salt in combination with wet 2,2'-dithiobis(benzothiazole) is substituted for dry 2,2'-dithiobis(benzothiazole).

Base catalysis of azolesulfenamides and sulfur to aminodithioazoles

The reaction of azolesulfenamides with sulfur to form aminodithioazoles is promoted by catalytic quantities of certain bases.

Rubber chemicals from cyclic amines- 6

This report describes the synthesis of modified morpholinodithio compounds and their evaluation as curing agents. It has been revealed that the electronic effect of substitution in thethiazole moiety on the curing properties of these compounds is not consistent. The unsubstituted 2- (4- morpholinodithio) benzothiazole 1 is superior to the 6- ethoxy, 5- chloro, or 6- nitro substituted derivatives in curing properties. Both the benzozazole and benzimidazole derivatives are inferior to the benzothiazole and 4- methyl thiazole analogs.
