- Abstract
2,2-Disubstituted 3-chloro-4-oxochromane-3-sulfenyl chlorides (2a,b) reacted with Lawesson's reagent (3) to afford the unprecedented 4-oxochromane phosphoro(dithioperoxo)thioic chlorides (5a,b) and not the β-thiooxo sulfenyl chlorides (6a,b). Whereas, sulfenyl chlorides (2a,b) gave 1,2,5,6-tetrathiocines (7a,b) along with 1,2,3,4-tetrathiins (8a,b) when they were treated with phosphorus pentasulfide. However, chlorination of 1,2,5,6-tetrathiocine (7a) with sulfuryl chloride afforded the 3,4-dichloro-3,4-disulfenyl dichloride (12) along with the 3,4-disulfenyl dichloride (13).
