Abstract
1 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, R5 and R6 is independently a hydrogen or hydrocarbyl, unsubstituted or substituted; Y1 is O or S; and Y2 is O or S.
Claims20
A compound of the formula (I):
- 11
- wherein:
- each of R1, R2, R3, R4, R5, and R6 is independently a hydrogen atom or a hydrocarbyl groups, provided that not more than two of R1 to R4 and not more than one of Rs and R6 are hydrogen;
- Y1 is O or S;
- and
- Y2 is O or S.
A compound of claim l.wherein each of R1, R2, R3, R4, R5, and R6 is independently an alkyl group of 1 to 30 carbon atoms, a cycloalkyl group of 3 to 7 carbons, an alkenyl group of 2 to 30 carbon atoms, an alkynyl group of 2 to 30 carbon atoms, an aryl group of 6 to 18 carbon atoms, or an aralkyl group.
