Abstract
Reaction of dialkylthioketenes with tetracyanoethylene oxide yields di cyanomethylenethiiranes in a sequence involving [3 + 2] cycloaddition, cycloreversion and rearrangement. In contrast, a thioketene with a su lfide moiety reacts preferentially on the latter to give the stable su lfur ylide 9.
