• For the preparation of <I>S</I>-vinylsulfilimines (<B>1</B>), mainly <I>S</I>-phenyl-<I>N</I>-tosyl-<I>S</I>-vinylsulfilimine, three routes were examined, <I>viz.</I>, (A) the reaction of vinyl sulfide with chloramine T, (B) that of 2-haloethyl phenyl sulfide with chloramine T followed by dehydrohalogenation, and (C) that of 2-hydroxyethyl sulfide with chloramine T followed by acetylation of the hydroxyl group and deacetoxylation. Route A has disadvantages of troublesome preparation of vinyl sulfides and low yield. Route B gives the precursor sulfilimine to <B>1</B> in good yield only by use of anhydrous chloramine T. Route C gives the best results in view of starting material and yield.
