  • Alkyl H-phosphonates of N,N?-dialkylimidazoliums and of quaternary ammoniums and uses thereof
    Patent number: 8309736
    Abstract: The application relates to the use of a salt associating an ammonium cation with an alkyl H-phosphonate anion of the following formula (I) in which R is a hydrocarbon radical, the pointed bond can be present or not, the radical R3 being then present or absent, as an ionic liquid. The ammonium cation is preferably an imidazolium cation. This ionic liquid is particularly useful in the field of green chemistry as a substitute for organic solvents. The application also relates to a method for preparing such a salt by the direct dealkylation of the corresponding dialkylphosphite by the appropriate nitrated base, in one step and without any solvent. The application also relates to a method for preparing mixed methylated phosphites.
