A compound comprising a sulfonated triorganophosphine of formula R1R2PR3[SO3M)]n, wherein R1 and R2 are selected individually from alkyl, aralkyl, and alicyclic groups; wherein R3 represents a branched divalent or polyvalent, alkylene or alicyclic radical that is bonded to the phosphorus atom and to one or more sulfonate substituents, and further wherein R3 does not contain any aryl moieties; M represents a monovalent cation; and n is an integer representing a total number of sulfonated substituents. The compound is useful as a ligand in transition metal-ligand complex catalysts that are capable of catalyzing the hydroformylation of an olefinically-unsaturated compound with carbon monoxide and hydrogen to form one or more corresponding aldehyde products. The ligand is incapable of alkyl-aryl exchange, thereby leading to reduced ligand usage and improving ligand and transition metal, e.g., rhodium, recovery and recycling, as compared with prior art ligands.
一种化合物,包括公式R1R2PR3[SO3M)]n的磺化三有机膦,其中R1和R2分别从烷基、芳基烷基和脂环基中选择;其中R3代表与磷原子和一个或多个磺酸取代基结合的支链二价或多价、烷基或脂环基团,且R3不含任何芳基;M代表一价阳离子;n是表示磺化取代基总数的整数。该化合物可用作过渡金属-配体复合催化剂中的配体,能够催化烯烃不饱和化合物与一氧化碳和氢反应,形成一个或多个相应的醛产物。该配体无法进行烷基-芳基交换,从而减少配体的使用量,改善配体和过渡金属(例如铑)的回收和循环,与现有技术的配体相比。
