[4+2] Cycloadditions of thiobenzophenones 1a and thiofluorenones 2 with cyclic and open‐chain dienes gave cycloadducts in high yields. Assignment of the product structure especially the regiochemistry of the cycloadditions involved 1 H‐ and 13 C‐NMR spectroscopy, and single‐crystal structure determination.
