ABSTRACT:
A process for synthesizing an aminosulfur trifluoride is provided. The process includes reacting a secondary amine with SF.sub.4 to produce the aminosulfur trifluoride product and a liquid amine-HF adduct. Substantially no solid amine-HF adduct is produced in the one-step reaction of the process. The reaction is conducted in a reaction solvent containing a tertiary amine. The process produces aminosulfur trifluorides, such as dialkyl, diaryl and arylalkyl aminosulfur trifluorides, in high yields.
