Bis(fluorosulfuryl)imide: a Brönsted acid catalyst for the addition of allyltrimethylsilane to carbonyl compounds
摘要:
The Bronsted acid HN(SO2F)(2) catalyses the addition of allyltrimethylsilane to carbonyl compounds to give the corresponding homoallylic alcohols in high yields.

direct conversion of light alkanes to aminated products by CH activation. Previous molecular systems reported for alkane amination operate by radical or nitrene-type reactions which generally result in unintended overfunctionalization. Here we disclose the first examples of direct conversion of methane and ethane to aminated products by C–H activation facilitated by electrophilic, main-group complexes dissolved

The present invention is directed to methods comprising adding ammonia to a sulfuryl fluoride solution to form the anion of bis(fluorosulfonyl)amine under conditions well suited for large-scale production. The bis(fluorosulfonyl)amine so produced can be isolated by methods described in the prior art, or isolated as an organic ion pair, such as an alkylammonium solid salt, or as an ionic liquid.
The invention relates to triazole salts, to their preparation and to applications thereof. The salts have at least one anionic triazolium group which carries at least one chlorosulphonyl, fluorosulphonyl or alkoxyfluorosulphonyl group, each of the anionic groups being combined with a proton or a cation that has a valency of less than or equal to 4. The salts are useful as synthesis reagents, as chemical-reaction or polymerization catalysts, and as ion-conducting materials for electrochemical generators, supercapacitors and electrochromic devices.

According to the method for producing bis(fluorosulfonyl)imide salt of the present invention, the method for producing fluorosulfate, and the method for producing bis(fluorosulfonyl)imide onium salt, first, an aqueous solution is prepared by dissolving a mixed liquid containing bis(fluorosulfonyl)imide and fluorosulfonic acid in water. Then, the aqueous solution is neutralized with an alkaline compound, producing bis(fluorosulfonyl)imide salt and fluorosulfate. In the methods, bis(fluorosulfonyl)imide salt, fluorosulfate, and bis(fluorosulfonyl)imide onium salt can be obtained safely and easily.
The present invention provides methods for producing bis(fluorosulfonyl) compounds of the formula:
F—S(O)2—Z—S(O)2—F I
by contacting a nonfluorohalide compound of the formula:
X—S(O)2—Z—S(O)2—X
with bismuth trifluoride under conditions sufficient to produce the bis(fluorosulfonyl) compound of Formula I, where Z and X are those defined herein.
