, p. 7579 - 7582 (2003)
A mild and convenient synthesis of monohydroxyphosphines has been achieved by epoxide ring-opening using primary or secondary phosphines in the presence of cesium hydroxide, 4 ? molecular sieves and DMF at room temperature. These reaction conditions were

Based on data for the acidity relationship of phosphines and phosphinous acids and water in dimethyl sulfoxide and water, a simple method is reported for the generation of phosphide and phosphinite anions by the action of concentrated aqueous alkali on primary and secondary phosphines as well as phosphinous acids in dimethyl sulfoxide or other dipolar aprotic solvents.Alkylation of the anion yields secondary and tertiary phosphines, polyphosphines, functionally substituted phosphines as well as similarly substituted phosphine oxides.Phosphinous acids have beenalkylated in various solvents in two-phase systems containing concentrated aqueous alkali and tetrabutylammonium iodide as phase transfer catalyst.
Carbonic Ester Phosphides - Synthesis and Cyclization Reactions

, p. 965 - 974 (2007/10/02)
Carbonic ester phosphides, RPHCOOR' and RP(COOR')2, have been prepared by the reaction of ClCOOR' with primary phosphines RPH2 in the presence of K2CO3.Some compounds of RPHCOOR' series are transformed into P-heterocycles through addition of the P-H group to the C=C doublebond systems.The 31P NMR data, IR and mass spectra of the novel compounds are presented and discussed. - Keywords: Carbonic Ester Phosphides, Mass Spectra, IR Spectra, NMR Spectra
