Abstract
The sterically crowded 2,2,4,4-tetramethyl-3-thioxocyclobutanone (7) and it s dithio analogue 9 were found to react readily with gaseous chlorine to af ford 1:1 and 1:2 adducts, respectively. The stable, crystalline products we re identified as the alpha-chlorosulfenyl chlorides 8 and 12 which yielded corresponding disulfides after treatment with equimolar amounts of thioacet ic acid.
