Free radical additions of diphenylphosphine, phenylphosphine and ethylenebis(phenylphosphine) to the following species are described: alkynols, alkyne ethers, unsaturated carboxylic acids and esters and beta-lactones. In a number of cases, these lead to water-soluble phosphines. NMR spectroscopic characterization of all new products has been carried out.
