THE REACTION OF SOME COMPOUNDS CONTAINING THIOAMIDE GROUPS WITH 2,4,6-TRICHLORO-1,3,5-TRIAZINE

Abstract

The reaction between some compounds containing thioamide groups and cyanuric chloride was investigated. Evidence is presented that the reaction proceeds on the thioamide sulfur and not on the nitrogen as postulated earlier. The reaction with thiourea was used for the preparation of trithiocyanuric acid, as well as for the preparation of 3-chloro-6(1H)-pyridazinethione or 3-mercapto-6(1H)-pyridazinethione, and presents a new and convenient method for the synthesis of these compounds.
