Usage

Uses

Trimethylsulfonium Tetrafluoroborate is used in mass connectivity index, a new molecular parameter for estimation of ionic liquid properties, and a much more easier concept for the calculation of connectivity indexes. Trimethylsulfonium Tetrafluoroborate also functions as a catalyst for oxidation reactions of hydrocarbons.

Polyfluoroalkylation of sulfides, phosphines, and stibines by phenylpolyfluoroalkyliodonium fluoroborates

The reaction of phenyl-1,1-dihydropolyfluoroalkyliodonium fluoroborates with triphenylphosphine, triphenylstibine, dimethyl sulfide, and p-chlorophenyl methyl sulfide gave the corresponding onium salts with the polyfluoroalkyl radical at the heteroatom.Phenylperfluorohexyliodonium fluoroborate reacts with tri(dimethylamino)phosphine with the formation of perfluorohexyltri(dimethylamino)phosphonium fluoroborate.

REARRANGEMENT OF BIS(ONIO)BENZOYLMETHYLIDE SALTS

The rearrangements of bis(onio)benzoylmethylide salts (ylide salts) on heating were investigated.It was established that migration of the methyl group to the oxygen occurs and that migration of the phenyl group to the oxygen only occurs in the case of triphenylphosphoniodiphenylselenoniobenzoylmethylide fluoroborate.Thermolysis of bisdimethylsulfoniobenzoylmethylide fluoroborate leads to the formation of trimethylsulfonium fluoroborate and 1,2-di(methylthio)-1,2-dibenzoylethylene.
