Procedure

A solution of 96 g (0.66 mole) of diethylaminotrimethylsilane in 100 ml trichlorofluoromethane was added dropwise to a solution of 40 ml (measured at -78°, 0.72 mole) of sulfur tetrafluoride in 200 ml of trichlorofluoromethane at -65° to -60°. The reaction mixture was warmed to room temperature and then distilled to give 88.86 g (84% yield) of diethylaminosulfur trifluoride as a pale yellow liquid, bp 46°-47° (10 mm).
