REACTIONS OF CARBON MONOXIDE WITH trans-Ir(CO)(Cl)(TPPMS)2 (TPPMS = PPh2(C6H4SO3K)) IN DMSO AND WATER, RATE AND MECHANISTIC STUDIES

Autor: David P. Paterniti, Jim D. Atwood

Publikováno v: Journal of Coordination Chemistry. 46:313-317

Reaction of CO with trans-Ir(CO)(Cl)L2 (L = PPh3 in toluene and DMSO; L = TPPMS in DMSO and H2O, TPPMS = PPh2(m-C6H4SO3Na)) reversibly produces Ir(CO)2(Cl)L2 or [Ir(CO)3L2]Cl depending on the solvent polarity. The solvent polarity has a small effect

Activation of Hydrogen on Iridium(I) Centers in Water: Solvent Effects, pH Effects, and Iridium−Hydride Exchange with D2O

Autor: Paul J. Roman, David P. Paterniti, Jim D. Atwood

Publikováno v: Organometallics. 16:3371-3376

The water-soluble iridium complexes trans-Ir(CO)L2X (X = Cl, OH; L = PPh2(m-C6H4SO3K) (TPPMS), P(m-C6H4SO3Na)3 (TPPTS)) have been used to extend the range of solvent effect for H2 activation at an iridium(I) center and to examine the effect of pH cha

Synthesis, Properties, and Reactions of Monosulfonated Triphenylphosphine (PPh2(m-C6H4SO3K) = TPPMS) Complexes of Iridium(I). Crystal and Molecular Structure of [N(CH2C6H5)(C2H5)3+][PPh2(m-C6H4SO3)-]·H2O

Autor: Ronald F. See, David P. Paterniti, and Melvyn Rowen Churchill, Jim D. Atwood, Paul J. Roman

Publikováno v: Organometallics. 16:1484-1490

Iridium complexes containing the TPPMS ligand (TPPMS = PPh2(m-C6H4SO3K)) have been prepared and studied in DMSO and H2O as a comparison to the PPh3 analogues in toluene. Measurements of the pH of the complexes show that most are almost neutral, but I

Laser Based Approaches to Increase Fiber-Optic-Based Selectivity: Dynamic Fluorescence Spectroscopy

Autor: Gino C. Catena, David P. Paterniti, Jingfan Huang, Kevin S. Litwiler, Frank V. Bright, Thomas A. Betts

Over the last several decades the communications industry has developed small, high-light transmitting fiber-optic materials. Because of their inherently non-perturbing nature fiber optics have found wide spread use in many diverse areas of analytica

Autor: Jim D. Atwood, Paul J. Roman, David P. Paterniti

Publikováno v: Chemical Communications. :2659

A significant enhancement in the rate of oxidative addition of H2 to square-planar iridium(II) complexes in water is observed; kinetic studies of the addition of H2 to trans-[Ir(CO)Cl(PPh3)2] in toluene and of H2 to trans-[Ir(CO)Cl{PPh2(C6H4SO3K-m)}2
