Reaction Steps

The method of Example 4 was used, using 7-hydroxytetradecan-8-one (22.8 g), propane-1,2-dithiol (10.8 g) and p-toluenesulphonic acid (0.5 g) to give 2,3-dihexyl-5,6-dihydro-5-methyl-1,4-dithiin as a greenish oil, bp 148°-155°/0.2 mm, yield 63%. NMR, 0.7-1.8 δ (multiplets), 2.05-2.35 δ (broad triplet), 2.45-3.6 δ (multiplets), 2.95 δ (doublet).
