Notes:
2H-Benzo[b]thiete (1) reacts in the o-quinoid form 1′ with the cyclic trithiocarbonates 4 and 6a, b and with the thioketones 8, 10 and 12 in [8π + 2π] cycloaddition reactions to the spiro compounds 5, 7a, b, 9, 11a, b. Irrespective of the presence of C=C double bonds, chemoselective and regioselective addition processes at the C=S double bonds take place that lead to 4H-1,3-benzodithianes.
