1,2-Ethanedithiol → HCID 86647240, compound

Participants

Reaction Steps

18.84 g (0.2 mole) of 1,2-ethanedithiol was introduced into 107.9 g (0.2 mole) of tetrakis(thietanylthio)tin prepared in Reference Preparation Example 3, and the resulting mixture was stirred at room temperature (20 degrees centigrade) for 2 hours. In order to remove the by-produced 3-mercaptothietane, methanol was introduced, each time of introducing in an amount of 100 g, and the resulting solution was stirred and washed. In this way, a separation operation was repeatedly carried out 8 times by decantation to precipitate a white solid. The precipitated solid was collected by filtration and dried to obtain 70.6 g (Yield: 84%) of bis(thietanylthio)dithiastannolane as a white crystal.
