Versuchsvorschrift

A mixture of 10 g (0.05 mole) of tris(dimethylamino)sulfonium chloride and 3.6 g (0.055 mole) powdered sodium cyanate in 100 ml methanol was stirred at room temperature (25°) for 3 days. Ether, 300 ml, was added, and the precipitated sodium chloride was filtered off. The filtrate was evaporated to dryness under reduced pressure and the residue was redissolved in acetonitrile, filtered, and then precipitated by the addition of ether. The precipitate was collected on a filter, washed with ether, and dried under dry nitrogen to give 9.27 g (90%) of tris(dimethylamino)sulfonium cyanate as a white crystalline powder, m.p. 202°-204°.
