Synthesis and application of sterically flexible and water-soluble phosphine ligands in palladium catalysis
… has focused on the design and synthesis of water-soluble phosphines for application in aqueous and biphasic palladium catalysis. Our group, through collaboration with the Dixon and Rogers groups, seeks also to better understand how phosphine ligand structure influences catalysis in order to …

Use of water-soluble phosphine ligands in heterogeneous hydroformylation catalysis : application to long-chain 1-alkenes
The two-phase rhodium-tri(m-sulfonatophenyl)phosphine (Rh-TPPTS) system for the hydroformylation of 1-octene, 1-decene, and 1-dodecene to the corresponding aldehydes, has been investigated. Due to the two distinct phases - the catalytic species in the aqueous phase and the products and reactants in …

Synthesis and hydrogenation of iridium complexes with bidentate and water-soluble phosphine ligands: developing novel water-soluble catalysts for hydrogenation of unsaturates
… bridge-splitting reactions with bidentate phosphine ligands to produce coordinatively unsaturated, 16 electron complexes of the form [Ir(COD)(P-P)]Cl (P-P = bidentate phosphine). Two bidentate ligands were examined: 1,2-bis(dimethylphosphino)ethane [DMPE] and 1,2-bis(diethylphosphino)ethane …

Hemilabile Phosphorus Enamine/Imine Ligands And Their Application In Ru-Catalyzed Aqueous Hydration Of Nitriles
… of PTA-Li gave a new series of P,N k2-enaminophosphine derivatives (PTA=C(R)NH2) of 1,3,5-triaza-7-phosphaadamantane (PTA), with a characteristic double bond on the PTA cage. Oxidation or sulfuration of the ligands resulted in a mixture of cis-trans products. The cis isomer of oxide converted …
