A procedure for the synthesis of 1,2-diamines from vinyl sulfonium salts and arylamines under mild conditions was developed. This present synthetic protocol not only obviates the need for a transition-metal catalyst and an oxidizing reagent but also features a broad substrates scope. The practicability of this protocol is demonstrated by the one-pot synthesis, a scale-up reaction, and transformations of the products to diverse N-heterocyclic compounds Mechanistic studies indicate that the formation of aziridine plays a key role during this diamination process. In the experiment, the researchers used many compounds, for example, 3-Bromo-5-chlorophenylamine (cas: 96558-78-0Quality Control of 3-Bromo-5-chlorophenylamine).
3-Bromo-5-chlorophenylamine (cas: 96558-78-0) 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). Commercially available organobromine pharmaceuticals include the vasodilator nicergoline, the sedative brotizolam, the anticancer agent pipobroman, and the antiseptic merbromin.
