Water Soluble Phosphines, Their Transitional Metal Complexes, and Catalysts
… use of special properties and effects of water as a solvent, and low environmental impact. For higher olefins (* C6), the reaction suffers low activity due to low water solubility of higher olefins. Tricesium analog of TPPTS, m,m,m-trisulfonated triphenylphosphine, was synthesized and …

Influence of solution ionic strength on aggregation of novel water soluble phosphines and two phase catalysis
The preparation of new water soluble phosphines for organometallic chemistry and catalysis in water is important to the development of environmentally benign homogeneous catalysts. A series of steric demanding surface active phosphines have been synthesized and fully characterized. Two phase …

Synthesis and Coordination Chemistry of Water-soluble Phosphines: Application to Ru-Catalyzed Hydration of Nitriles in Aqueous and Biphasic Media
… and their ruthenium arene complexes as potential water-soluble catalysts for aqueous and biphasic hydration of nitrile. A series of upper-rim modified PTA derivatives were prepared by reaction of lithiated PTA with various electrophilic substrates, including aldehydes, ketones, imines and CO2. …

Hemilabile Phosphorus Enamine/Imine Ligands And Their Application In Ru-Catalyzed Aqueous Hydration Of Nitriles
… and ruthenium arene complexes of these new water soluble phosphines were also synthesized. The ligands coordinated in a k2-P,N bidendate fashion to the metal centers to give new iminophosphine complexes. Upon coordination to the metal centers, the ligands were shown to isomerized and …

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 …

Synthesis and hydrogenation of iridium complexes with bidentate and water-soluble phosphine ligands: developing novel water-soluble catalysts for hydrogenation of unsaturates
… These compounds have been found to be both water soluble and reactive towards molecular hydrogen at room temperature, qualities that make them ideal for serving as catalysts for the aqueous hydrogenation of unsaturates. Water-soluble ligands were also allowed to react with [Ir(COD)Cl]₂. In …
