  • Patent number: 8466306
    Abstract: A compound comprising a sulfonated dihydrocarbyl(arylalkyl)phosphine of formula R1R2PR3—(SO3M)n, wherein the R1 and R2 are selected individually from alkyl, aralkyl, and alicyclic groups, and R3 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.
