| abstract |
The invention relates to oxonium salts with [(Ro)3O]+ cations and sulfonium salts with [(Ro)3S]+ cations, wherein Ro represents straight-chain or branched alkyl groups with 1-8 C atoms or unsubstituted phenyl or phenyl that is substituted with Ro, ORo, N(Ro)2, CN or halogen, and anions that are selected from the group of [PFx(CyF2y+1-zHz)6-x]- anions with 2<=x<=5, 1<=y<=8 and 0<=z<=2y+1, or anions selected from the group of [BFn(CN)4-n]- anions with n = 0, 1 , 2 or 3, or anions selected from the group of [(Rf1SO2)2N]- anions or anions selected from the group of [BFwRf2 4-w]- anions. The invention also relates to a method for producing said salts, and to their use, especially in the production of ionic liquids. |
