This chapter gives an account of the newer developments on the synthesis and reactivity of phosphine chalcogenides, mainly oxides and sulfides. A series of new synthetic methods for phosphine oxides is discussed, followed by preparations utilizing simple P-reagents such as P(iii)- and P(v)-chlorides, and >P(O)H species.

Tris(n-butyl)phosphine, Tris(tert-butyl)phosphine and Tris(trimethylsilyl)phosphine
Acta Crystallographica Section C Crystal Structure Communications, 1995Single crystals of the title compounds, C 12 H 27 P (1), C 12 H 27 P (2), and C 9 H 27 PSi 3 (3), were grown in capillaries at low temperature using zone-melting techniques [Brodalla, Mootz, Boese & Osswald (1985). J. Appl. Cryst. 18, 316-319]. The molecular and crystal structures of all three compounds were determined at 102 K.

(Ferrocenylmethyl)phosphine, an air-stable primary phosphine
Journal of the Chemical Society, Dalton Transactions, 1999Removal of formaldehyde from the readily prepared ferrocenyl (R) hydroxymethylphosphine RCH2P(CH2OH)2 with one mole equivalent of Na2S2O5 gave the completely air-stable primary phosphine RCH2PH2 as a crystalline, sublimable solid. With [Mo(CO)6] both mono-, [Mo(CO)5(RCH2PH2)], and di-substituted, [Mo(CO)4(RCH2PH2)2], products are readily formed, and ...

Microemulsions with Alkyldimethyl Phosphine Oxides and Alkyldiethyl Phosphine Oxides
Langmuir, 2008Alkyldimethyl phosphine oxides (C n DMPO) as well as alkyldiethyl phosphine oxides (C n DEPO) with chain lengths of n = 10 (decyl), 12 (dodecyl), and 14 (tetradecyl) were synthesized and purified to study how the formation of microemulsions depends on the size of the headgroup and on the length of the alkyl chain.

From phosphine-promoted to phosphine-catalyzed reactions by in situ phosphine oxide reduction
Tetrahedron Letters, 2016Abstract The well-known stoichiometric phosphine-promoted reactions such as the Wittig, Mitsunobu, Staudinger, Appel reactions, and others are widely used in organic chemistry. Recently, many efforts have been made to render these reactions catalytic in phosphine.
