A compound comprising a sulfonated triorganophosphine of formula R
1
R
2
PR
3
[SO
3
M)]
n
, wherein R
1
and R
2
are selected individually from alkyl, aralkyl, and alicyclic groups; wherein R
3
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 R
3
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.
