Ethyl hexafluoroantimonate

A hydrophobic IL, 1-butyl-3-decylimidazolium hexafluoroantimonate [dbim][SbF6], was then chosen for particle impregnation, thus creating a lipophilic environment around the particle where reactions can take place. Thus, 42 is added to a solution of dbim SblvJ in ethyl acetate to give, after solvent removal under reduced pressure, a fine powder of SiO2-Sc-IL (43). 

Ene reaction. An expedient route to chiral a-hydroxy esters is based on the ene reaction of alkenes with ethyl glyoxylate in the presence of (5)-BINAP-(bisacetonitrile)-palladium hexafluoroantimonate. The tolyl-BINAP analogue is an even better ligand. 

Oxman et al., smdied controlled, sequentially curable cationic/free radical hybrid photopolymerization of diepoxide/acrylate hybrid material with the aid of photodifferential scanning calorimetry. The polymerizations were carried out in the presence of various concentrations of either ethyl-4-dimethylamino benzoate or 4-tert-butyl-N,N,-dimethylaniline as electron donors and camphoquinone/diphenyliodonium hexafluoroantimonate as the sensitizing system. The results showed that the free-radical acrylate reactions always precede the cationic epoxy polymerizations. 

In 1999, Huh et published a study on the cationic ROP of 3-ethyl-3-(hydroxymethyl)oxetane (EHO). A convenient method for the preparation of the respective hyperbranched polyether by thermally induced bulk polymerization was introduced. The sulfonium salt initiator 1-benzyltetrahydrothiophen-1-ium hexafluoroantimonate was used in this approach (Scheme 8).
