| 20100234642 | NAPHTHENIC HYDROCARBON ADDITIVES FOR DIARYL PHOSPHIDE SALT FORMATION - The invention relates to the use of polycyclic aromatic hydrocarbons (PAHs) such as naphthalene and its alkyl, aryl, or heteroatom substituted analogs, that act as catalysts in the presence of an alkali metal (Li, K, Na) for the reduction of electron-deficient and electron-rich triaryl phosphines to their corresponding alkali metal diaryl phosphide salts. The process is also useful for the catalysis of triaryl phosphine chalcogen adducts such as the sulfides, oxides, and selenides, diaryl(halo)phosphines, triaryl phosphine-borane adducts, and tetra-aryl bis(phosphines) that can also be reduced to their corresponding alkali metal diaryl phosphide salts. The invention also relates to small molecule PAHs and polymer tethered PAHs naphthenics. | 09-16-2010 |
| 20110065961 | PROCESS FOR PRODUCTION OF PHOSPHINE DERIVATIVE FROM PHOSPHINE OXIDE DERIVATIVE - Disclosed is a process for producing a phosphine derivative from a phosphine oxide derivative, which comprises the following steps: (I) mixing a phosphine oxide derivative represented by formula (1) with a chlorinating agent in a polar organic solvent to cause the reaction between these components; and (II-1) adding a salt of a metal having an ionization tendency equal to or lower than that of aluminum to the reaction mixture and carrying out the reductive reaction in the presence of aluminum or (II-2) subjecting the reaction mixture to electrolytic reduction, thereby producing a phosphine derivative represented by formula (2).
