Monosulfonated triphenylphosphane

Another, similar propene hydroformylation process with rhodium and monosulfonated triphenylphosphane (tppms) was reported recently by Union Carbide (139). Capacity data are not available. 

Triphenylphosphane monosulfonate (sodium salt) and triphenylphosphine disulfonate (disodium salt) were compared in one study with TPPTS and the results showed that each ligand together with 1.0mol% palladium catalyst is similarly effective for the Mizoroki-Heck reaction of iodobenzene with an olefin [162], Leaching levels are also comparable the percentaged leaching represents the amount of palladium contamination...
