    • A compound comprising a sulfonated dihydrocarbyl(arylalkyl)phosphine of formula R 1 R 2 PR 3 -(SO 3 M) n , wherein the R 1 and R 2 are selected individually from alkyl, aralkyl, and alicyclic groups, and R 3 is a divalent or polyvalent arylalkylene radical such that the alkyl moiety is bonded to the phosphorus atom and the aryl moiety is bonded to the alkyl and is also substituted with one or more sulfonate groups; M is a monovalent cation, and n ranges from 1 to 3. 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 improved ligand and transition metal, e.g., rhodium, recovery and recycling.
    • 包含式R 1 R 2 PR 3 - (SO 3 M)n的磺化二烃基(芳烷基)膦的化合物,其中R 1和R 2分别选自烷基,芳烷基和脂环基,R 3是二价或多价芳基亚烷基,使得烷基部分 键合到磷原子上,芳基部分键合到烷基上并且也被一个或多个磺酸基团取代; M是一价阳离子,n在1至3的范围内。该化合物可用作过渡金属 - 配体配合物催化剂中的配体,其能够催化烯属不饱和化合物与一氧化碳和氢气的加氢甲酰化形成一个或多个 更多相应的醛产品。 配体不能进行烷基 - 芳基交换,从而导致配体使用减少,改进配体和过渡金属,例如铑,回收和回收。
