Selective C-P(O) Bond Cleavage of Organophosphine Oxides by Sodium

Sodium exhibits better efficacy and selectivity than Li and K for converting Ph3P(O) to Ph2P(OM). The destiny of PhNa co-generated is disclosed. A series of alkyl halides R4X and aryl halides ArX all react with Ph2P(ONa) to produce the corresponding phosphine oxides in good to excellent yields.

Selective reaction of trialkylaluminum with organophosphorus dihalide

Organophosphorus dihalides can have one of their halogen substituents substituted with an alkyl group from a trialkylaluminum by gradual addition of the latter reagent to the former.

ALKYLATION IN SITU OF ARYLPHOSPHINES FORMED DURING THERMOLYSIS OF HYDROPHOSPHORYL COMPOUNDS

In the course of the thermolysis (ca. 200 deg C) of diorganophosphonous and phenylphosphonous acids in the presence of alkyl halides, polyalkylation products are obtained - dialkyldiphenyl- and trialkylphenylphosphonium salts and dialkylphenylphosphine oxides.Combined with alkaline splitting of the phosphonium salts, it is possible to synthesize dialkylphenyl- and trioctylphosphine oxides from available hydrophosphoryl compounds using these reactions.

SYNTHESE ET STRUCTURE D'OXYDES ET DIOXYDES DE PHOSPHINES TERTIAIRES

Tertiary phosphine oxides have been prepared in excellent yield from primary alkyl halides and dihalides or aromatic halides and activated sodium phosphinates obtained by reaction of dialkyl phosphine oxides with complex bases (NaNH2/tBuONa).We have studied by 13C NMR the structure of these compounds.We have reported more particularly the influence of carbon atoms number between the two phosphorus in the case of dioxides and the influence of some parameters such as the temperature and the solvent on the NMR spectra.
