Abstract (en)
[origin: WO02079212A1] Novel phosphonium phosphinate compounds and their methods of preparation are disclosed. Phosphonium salts are ionic liquids that are useful as polar solvents. The novel phosphonium phosphinate compounds have general formula (I), wherein R1, R2, R3, R4, R<5> and R6 is independently a hydrogen or hydrocarbyl, unsubstituted or substituted; Y1 is O or S; and Y2 is O or S.
