With a view to synthesize 2-(trifluoromethylthio)-1, 3-dithiane (1), 1, 3-dithiane (2) was reacted in dry pentane at− 78° C under dry N2 with trifluoromethylsulfenyl chloride (3) and was found to furnish the desired compound in poor yields along with ten other compounds. Under similar conditions, 2-lithio-1, 3-dithiane on treatment with 2 and bis-(trifluoromethyl) disulfide (4) gave 8.0% and 10.0% yields of 1, respectively. In connection with this study,( ...
