## Abstract Thione __S__โ€oxides (sulfines) harbor the allyl anion MO of 1,3โ€dipoles, but fail to undergo 1,3โ€cycloadditions to the usual dipolarophiles with a CC multiple bond. Thioketones stand the test as __superdipolarophiles__. The thione __S__โ€oxides 3 and 9 combined with the thioketones 5 and

## Abstract Surprisingly, thiobenzophenone __S__โ€oxide (5) and thione 6 afforded the spiroโ€1,2,4โ€trithiolane 7 (86%) instead of the expected spiroโ€1,2,4โ€oxadithiolane 16.
