Synthesis of N-sulfenylimines from disulfides and primary methanamines was written by Kawecki, Robert. And the article was included in Journal of Organic Chemistry in 2022.Reference of 128-08-5 This article mentions the following:
N-sulfenylimines (sulfenimines, thiooximes, N-alkylidenesulfenamides) were efficiently synthesized through the reaction of primary amines and disulfides with NBS or bromine. This reaction can be carried out in an open flask at room temperature without the need for any transition metal-containing additives. The use of thiols instead of disulfides gave similar results. A wide range of amines were reacted with aryl and alkyldisulfides, resulting in the formation of sulfenimines in a yield of 44-99%. In the experiment, the researchers used many compounds, for example, 1-Bromopyrrolidine-2,5-dione (cas: 128-08-5Reference of 128-08-5).
1-Bromopyrrolidine-2,5-dione (cas: 128-08-5) belongs to organobromine compounds. Organo bromine compounds are versatile compounds and are widely used in diverse fields. Organo bromine derivatives are used in the dye sector, as an indicator in analytical chemistry (Bromothymol blue is a popular indicator). Many of the alkyl bromine derivatives are excellent alkylating agents since bromides are good leaving groups. Tribromides, like tetrabutylammonium tribromide, are used as a solid source of bromine. N-bromosuccimide (NBS) is used for the selective bromination of allylic bonds.Reference of 128-08-5
