Abstract
A process for the preparation of 2-hydroxyethylphosphines. The process involves the addition of an alkenyl carboxylate (such as vinyl acetate) to a phosphine containing a P--H bond, followed by conversion of the resulting ester-substituted phosphine to the corresponding 2-hydroxyethylphosphine. The conversion is effected by alcoholysis or by hydrolysis.
