Water-soluble electron-donating phosphines: sulfonation of …
WebSulfonation of PPh 3 gives tris(3-sulfophenyl)phosphine, P(C 6 H 4-3-SO 3 −) 3 , usually isolated as the trisodium salt. In contrast to PPh 3 , TPPTS is water-soluble, as are its metal derivatives. Rhodium complexes of TPPTS … WebThis compound stands out as a leading option for many applications due to the high reactivity and the ability to initiate under both ultraviolet and violet light sources. Properties Water solubility: 4.7 wt% λ max: 380 nm (UV and 350-410 nm violet light curing) High reactivity formulations Biocompatible Recommended addition level: 0.1 – 0.8 wt% Phosphine dissolves more readily in non-polar solvents than in water because of the non-polar P−H bonds. It is technically amphoteric in water, but acid and base activity is poor. Proton exchange proceeds via a phosphonium ( PH + 4 ) ion in acidic solutions and via phosphanide ( PH − 2 ) at high pH, with … See more Phosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula PH3, classed as a pnictogen hydride. Pure phosphine is odorless, but technical grade samples have a highly See more Philippe Gengembre (1764–1838), a student of Lavoisier, first obtained phosphine in 1783 by heating white phosphorus in … See more Phosphine may be prepared in a variety of ways. Industrially it can be made by the reaction of white phosphorus with sodium or potassium hydroxide, producing potassium or See more Deaths have resulted from accidental exposure to fumigation materials containing aluminium phosphide or phosphine. It can be absorbed either by inhalation See more PH3 is a trigonal pyramidal molecule with C3v molecular symmetry. The length of the P−H bond is 1.42 Å, the H−P−H bond angles are 93.5°. The dipole moment is 0.58 D, which increases with substitution of methyl groups in the series: CH3PH2, 1.10 D; (CH3)2PH, 1.23 D; … See more Organophosphorus chemistry Phosphine is a precursor to many organophosphorus compounds.
