The present invention provides phosphinic acids and their sulfur derivatives, in accordance with the following formula (I): wherein R
1
and R
2
are different and each of R
1
and R
2
is independently selected from an organic radical that branches at the alpha carbon and an organic radical that branches at the beta carbon, and each of X and Y is independently O or S, and wherein said compound is a liquid at room temperature. Compounds of formula (I) find utility for example as metal extractants. Also provided are methods for making compounds of formula (I) and their corresponding phosphine intermediates.
