The dipolar cycloaddition of thiobenzophenone S ‐oxide ( 1 ) and 2,2,4,4‐tetramethyl‐3‐thioxocyclobutanone ( 2 ) generates the labile 1,2,4‐oxadithiolane I , which in the presence of trans ‐cyclooctene ( 3 ) affords trans ‐episulfide ( 9 ). In this direct sulfur transfer, the oxathiirane II and/or the dithiirane IV , both derived from the 1,2,4‐oxadithiolane I , are proposed as elusive episulfidating agents.
