  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。

  The present invention relates to ligands and catalyst systems for the hydroformylation of short and long chain olefins, preferably for the hydroformylation of ally alcohol producing 4-hydroxybutyraldehyde. The ligands disclosed herein are all-trans phosphinomethyl-cyclobutane ligands, such as, for example, all-trans- 1,2,3, 4-tetra[bis-(3, 5-xylyl)phosphinomethyl]-cyclobutane. The catalyst systems comprise these all-trans phosphinomethyl-cyclobutane ligands in combination with an organometallic rhodium complex such as, e.g., (acctylacetonato)-dicarbonyl-rhodium (I). The ligands and catalyst systems of the present invention may be employed in the hydroformylation of olefins, in particular in the hydroformylation of allylalcohol, and provide improved selectivity and high reaction yields. wherein R1 is alkyl, preferably methyl, ethyl or propyl, R2 is H or an alkoxy group, R3 and R4, independently of one another, CH2OR1, CH2O-aralkyl, CH2OH,CH2-[P(3,5-R1,R1-4-R2-phenyl)2] or CH2O-(CH2-CH2-O)m-H (with m being an integer between 1 and 1.000).

  本发明涉及短链和长链烯烃的配体和催化剂体系，优选用于产生4-羟基丁醛的丙烯醇的氢甲酰化反应。本文所述的配体是全反式膦甲基环丁烷配体，例如全反式-1,2,3,4-四[双-(3,5-二甲苯基)膦甲基]-环丁烷。该催化剂体系包括这些全反式膦甲基环丁烷配体与有机金属铑配合物，例如(acctylacetonato)-二羰基-铑(I)。本发明的配体和催化剂体系可用于烯烃的氢甲酰化反应，特别是在丙烯醇的氢甲酰化反应中，提供了改进的选择性和高反应产率。其中R1是烷基，优选是甲基、乙基或丙基；R2是氢或烷氧基；R3和R4彼此独立，是CH2OR1、CH2O-芳基烷基、CH2OH、CH2-[P(3,5-R1,R1-4-R2-苯基)2]或CH2O-(CH2-CH2-O)m-H（其中m是介于1和1.000之间的整数）。
