9-Fluorenethione <I>S</I>-<I>p</I>-toluenesulfonimide reacted with diphenylketene to give two regioisomeric 1,3-dipolar cycloadducts. The thione <I>S</I>-imide and symmetrical dialkylcarbodiimides produced 3-tosylimino-1,2,4-thiadiazolidines. In the reaction with ketenimines, there occurred siteselective cycloaddition reactions on C=N <I>vs.</I> C=C bonds in the imines and further rearrangement of the 1,2,4-thiadiazolidine adducts.
