147-nm Photolysis of phosphine and phosphine-d3
The Journal of Physical Chemistry, 1981The 147-nm photodecompositions of PH/sub 3/ and PD/sub 3/ result in the formation of H/sub 2/ (D/sub 2/) and P/sub 2/H/sub 4/ (P/sub 2/D/sub 4/) in the gas phase and a solid deposit which is probably a mixture of phosphorous and polymeric phosphorous hydrides (PH)/sub x/ and (PD)/sub x/.

(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.

The basicity of phosphines [PDF]
Canadian Journal of Chemistry, 1982 The basicities of the triarylphosphines P(4-XC6H4)3 (X = Cl, F, H, CH3, CH3O, (CH3)2N), P(3-CH3C6H4)3, and P(2-CH3C6H7)3 as well as the trialkylphosphines P(t-Bu)3 and PCy3 have been measured by the nitromethane titration method. The range of basicity available by aryl substitution is very large, being pKa = 8.65 for X = (CH3)2N to 1.03 for X = Cl ...

The preparation of phosphinic chlorides from phosphinic amides
Journal of the Chemical Society, Perkin Transactions 1, 1972Phosphinic and phosphinothioic amides react with hydrogen chloride in a suitable inert solvent at room temperature to give high yields of the corresponding phosphinic or phosphinothioic chlorides.

Bis(cyclopropenium)phosphines: Synthesis, Reactivity, and Applications.
Chemistry, 2016A straightforward route for the preparation of a set of bis(cyclopropenium)-substituted phosphines is reported. Due to their dicationic nature, these ligands depict an excellent π-acceptor character.
