Abstract
This invention relates to water soluble phosphines of the following structural formula and method of preparing these phosphines: Wherein A is a moiety which is stable to the reaction conditions and does not interfere with solubility of the compound in the preparation reaction. R1 and R2 are selected from hydroxyl groups, dialkylamino group, and alkoxide groups.
Claims19
