Trifluoromethylsulfuric

In the preparation of trifluoromethylsulfur trifluoride, the chloride must be dissolved in a fully halogenated solvent to prevent explosion during treatment with chlorine fluoride or chlorine trifluoride.

Although a-chloromethyl- °° and -ethylsulfur chloride reacted with a mol equivalent of carbazole at each electrophilic site giving 72 (R = H and Me),202 trifluoromethylsulfur chloride would react only with the Grignard derivative of carbazole, giving 73. ° ... 

When treated with chlorine trifluoridc in CFC-12 at — 78 C, trifluoromethanesulfenyl chloride and bis(lrifluoromethyl) disulfide are transformed into trifluoromethylsulfur trifluoride (95%) and bis(trifluoromethyl)sulfur difluoride (90%). respectively.121... 

Cobalt(III) fluoride is useless for the fluorination of nonfluorinated sulfur(II) compounds as it leads to the elimination, or near elimination of sulfur. However, the older literature106 claims that methanethiol can be fluorinated to trifluoromethylsulfur pentafluoride over cobalt(III) fluoride. 

Most experiments were performed with cotton or cotton linters as highly crystalline celluloses. Table I shows conditions leading to complete dissolution. A minimum amount of an acid which forms a cellulose ester (sulfuric or trifluoromethylsulfuric acid) (Entries 5 7-14) is necessary for the reaction. The dissolution is accelerated by a temperature increase (Entries 10-12 13, 14) and leads to water-soluble cellulose acetate hydrogensulfate. Whereas this primary hydrolysis can be achieved within 1-5 min, the deesterification and complete hydrolysis of the soluble cellulose derivative proved to be much more difficult. This is in contrast to the generally accepted view that the main resistance to the hydrolysis of cellulose lies in the crystalline nature or low accessibility determining the heterogeneous first step of the reaction.
