10. Dibenzoylacetylene (3) was prepared according to the literature, see: J. J. Zhang and G. B. Schuster, J. Am. Chem. Soc., 1989, 111, 7149.
11. It has been noted previously that the reaction between 1 and 3 failed to give 4, 5-dibenzoyl-1, 3-dithiole-2-thione, see: M. Ahmed, J. M. Buchshriber and D. M. McKinnon, Can. J. Chem., 1970, 48, 1991.
12. The unexpected formation of thiopyran-4-chalcogenone derivatives has been observed previously and was explained by the stability of the thiopyran-4-chalcogenone systems, see: C. J. Grol, Tetrahedron, 1974, 30, 3621.
13. Crystal structures of thiopyran-4-ones have been reported, see for example: (a) C. H. Chen, G. A. Reynolds, D. L. Smith and J. L. Fox, J. Org. Chem., 1984, 49, 5136;

16. This kind of equilibrium has been described in the literature, see for example; J. D. Coyle, P. A. Rapley, J. Kamphuis and H. J. T. Bos, J. Chem. Soc., Perkin Trans, 1, 1986, 2173.
17. A number of similar [4 + 2] cycloadditions of related structures of III and alkynes, to give spiro-thiopyrans (related to IV) have been reported, see for example: (a) E. Fanghänel, T. Palmer, J. Kersten, R. Ludwigs, K. Peters and H. G. Schnering, Synthesis, 1994, 1067;

20. To our knowledge transchalcogenation of thiopyran-4-thiones using mercuric acetate in chloroform and glacial acetic acid, have apparently not been reported, although this method has been widely used for transchalcogenation of 1, 3-dithiole-2-thipnes to the corresponding 1, 3-dithiole-2-ones, see N. Svenstrup and J. Becher, Synthesis, 1995, 215.
