Abstract

A practical method for the synthesis of diamino trisulfides was reported by Katritzky employing the reaction of diamino disulfides with sulfuryl chloride, sodium sulfide nonahydrate and sodium hydroxide. 6 The method is applicable to bis(N,N-dialkylamino)disulfides or bis(N,N-diallylamino )disulfides with yields of the trisulfides ranging from 47 to 81%. However, N-aryl substituted aminodisulfides give poor results because of the reaction of the aromatic rings with sulfuryl chloride.
