Acetylthiosulfenyl chloride

The reaction of tetramethylallene with acetylthiosulfenyl chloride gave 2-acetyl-thiosulfenyl-1,3-diene 35 [21a],... 

Several types of sulfenyl chlorides are known. Sulfur monochloride and dichloride can add to dienes forming sulfor bridges. - The most commonly used sulfenyl halides are benzenesulfenyl dilorides and methanesulfenyl chloride. Other sulfenyl halides, such as acetylthiosulfenyl chloride and thiocyanogen chloride, have been added to alkenes, but few subsequent transformations have been carried out with those intermediates. 8... 

The Zran.v-stereoselective addition to a C-C double bond is also observed with acyl- and aminosulfenyl chlorides. For example, the reaction of acetylthiosulfenyl chloride with acenaph-thene affords the t/wu-adduct 6 only22.
