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.
本发明涉及使用多环芳烃(PAH),例如萘及其烷基,芳基或杂原子取代的类似物,作为催化剂存在碱金属(Li,K,Na)的情况下,将电子亏损和电子富集的三芳基膦还原为相应的碱金属二芳基膦盐。该过程还可用于三芳基膦硫族加合物(如硫化物,氧化物和硒化物),二芳基(卤素)膦,三芳基膦硼烷加合物和四芳基双(膦)的催化,这些化合物也可以被还原为相应的碱金属二芳基膦盐。本发明还涉及小分子PAH和聚合物拴链PAH萘烷。
