METHOD FOR PREPARING BIS(FLUOROSULFONYL)IMIDE

The invention relates to a method of preparing lithium bis(fluorosulfonyl)imide, comprising: reacting lithium bis(chlorosulfonyl)imide with an alkali metal fluoride used as a fluorinating agent in a solvent of saturated alkyl carbonate and/or saturated fluoroalkyl carbonate in the presence of a crownether phase transfer catalyst adaptive to the alkali metal fluoride to obtain lithium bis(fluorosulfonyl)imide. The method of preparing lithium bis(fluorosulfonyl)imide according to the invention possesses a simple process route, and industrial manufacture can be realized easily.

Ion chemistry of sulfuryl fluoride: An experimental and theoretical study on gas-phase reactions involving neutral and ionized SO2F2

The gas phase ion chemistry of sulfuryl fluoride is studied by ion trap mass spectrometry and ab initio calculations. Reactions of ions of atmospheric relevance with neutral SO2F2 mainly result in SO 2F2 depletion by dissociative electron transfer. In few cases, a different reaction mechanism involving F-abstraction is invoked, since dissociative ion products are observed despite the electron transfer channel being endothermic. Ab initio calculations revealed a nearly perfect distonic structure for the molecular SO2F2+ ion, whose capability of activating strong HX bonds (X = C, N, O) is ascribable to the high spin density located on the oxygen atoms, in line with literature reports. Among the ions produced by electron ionization of SO2F2, the FSOx+ (x = 0-2) ions are capable of activating the HNH2 bond of ammonia. Theoretical investigation revealed that NH 3 activation by SF+ requires a triplet to singlet conversion along the reaction pathway. This conversion is expected to be fast, the conceivable reaction rate determining step being the subsequent intramolecular hydrogen migration.

Thermally persistent fluorosulfonyl nitrene and unexpected formation of the fluorosulfonyl radical

Thermally persistent triplet sulfonyl nitrene, FSO2N, was produced in the gas phase in high yields (up to 66%) by flash vacuum pyrolysis of FSO2N3. Surprisingly, no rearrangement of FSO 2N was observed, but the
