Abstract

Experimental Section Tetraethylsulfamide (4b). The following procedure proved to be con~enient.'~ A solution of sulfuryl chloride (76.6 mL, 0.946 mol) in pentane (100 mL) was added dropwise to a stirred solution of diethylamine (392 mL, 3.78 mol) in pentane (400 mL) that was cooled in an ice bath. After the addition was complete, the reaction mixture was allowed to warm to ambient temperature. Additional diethylamine (100 mL) was added, and the mixture ...
