Reactions of Geminal Dithiolates with (Z)-1,4-Dichloro-but-2-eneGeminal dithiolates 2 and 7 react with (Z)-1,4-dichloro-but-2-ene either to give 4-vinyl-1,3-dithiolanes 3 or 4, 7-dihydro-1,3-dithiepines 4 and 8, respectively. Another method for the synthesis of 4 and 8 is the reaction of ketene dichlorides 5 or isocyanide dichloride 9 with the disodium salt of (Z)-but-2-ene-1,4-dithiol. The formation of the corresponding 1,3-dithiolanes can be excluded in these cases. 1H- and 13C-n.m.r. spectra are in accordance with the structures and are discussed.
