Abstract (en)
[origin: EP1634867A1] Production of nitrogen, phosphorus, sulfur or oxygen-containing organic cation tricyanomethanide salt ionic liquids (I) involves mixing malonic acid dinitrile (II) and a cyanogen compound (III) in presence of base, optionally in a solvent; and adding an organic cation salt (IV), such that the anion of (IV) is exchanged in an aqueous phase with the tricyanomethanide anion formed in situ from (II) and (III). Production of organic cation tricyanomethanide salt ionic liquids of formula Q +>.C(CN) 3 -> (I) involves: (1) mixing malonic acid dinitrile (II) and a cyano compound of formula RCN (III) in presence of base, optionally in a solvent; and (2) adding an organic cation salt of formula (Q +>) n.X n-> (IV), such that the anion X n-> is exchanged in an aqueous phase with the tricyanomethanide anion formed in situ from (II) and (III). Q +>organic cation of formula W +>R 1>R 2>R 3>R 4>, N +>R 5>R 6>R 7>, S +>R 9>R 10>R 11> or Z +>R 11>R 12>; W : N or P; R 1> - R 3>alkyl; R 4>alkyl, cycloalkyl or aryl; or WR 1>R 2>5-7 membered ring (in which case R 3>, R 4> = alkyl); or WR 1>R 2> and W 3>R 4>5-7 membered rings; NR 5>R 6>ring; R 7>alkyl, cycloalkyl or aryl; R 8>, R 9>alkyl or together complete a ring; R 10>alkyl, cycloalkyl or aryl; Z : O or S; R 11>, R 12>together complete a ring; R : Cl, Br, I or CN; n : 1 or 2; X n->halide, pseudohalide, sulfate or organic acid anion; all rings formed by R 1> - R 12> optionally (i) are substituted by one or more of alkyl, alkoxy, cycloalkyl, aryl, halo or CN, (ii) contain 1 or 2 additional O, S or N heteroatoms and/or (iii) are fused to an aromatic or non-aromatic 5-7 membered ring; all alkyl moieties have 1-20C, cycloalkyl moieties 3-10C and aryl moieties 6-10C; all alkyl, cycloalkyl or aryl moieties are optionally substituted by one or more halo.
