Reaktionsschritte

3 ml (14.4 mmoles) of hexamethyldisilazane were added to a refluxing mixture of 2.48 g (20 mmoles) of N,N-dimethylsulfamide, 9 mg (0.05 mmole) of saccharin and 30 ml of toluene. By the method described hereinbefore, it was established that the calculated amount of ammonia had been evolved after refluxing for one hour and volatile materials were then evaporated under reduced pressure. The residue was dried to room temperature to obtain 3.96 g (101%) of N,N-dimethyl-N'-trimethylsilylsulfamide melting at 83°-86° C.
