Phosphine Oxide Derivative as a Passivating Agent to Enhance the Performance of Perovskite Solar Cells
Mohammad Khaja Nazeeruddin, Mounir Driss Mensi, Hiroyuki Kanda, Aron Joel Huckaba, Valentin Ianis Emmanuel Queloz, Albertus Adrian Sutanto, Hobeom Kim, Cansu Igci
Defects of metal-halide perovskites detrimentally influence the optoelectronic properties of the thin film and, ultimately, the photovoltaic performance of perovskite solar cells (PSCs). Especially, defect-mediated nonradiative recombination that occurs at ...
2021Development of Catalytic Asymmetric C-H Functionalizations with Chiral Cyclopentadienyl Iridium(III) Complexes
Cp*Ir(III) catalyzed C-H functionalization is a growing field, since it provides novel complementary reactivities, but enantioselective C-H functionalization reactions with this metal remain a niche. This thesis investigates CpXIr(III) catalyzed asymmetric ...
EPFL2019Access to P- and Axially Chiral Biaryl Phosphine Oxides by Enantioselective (CpIrIII)-Ir-x-Catalyzed C-H Arylations
Nicolai Cramer, Julia Pedroni, Yun-Suk Jang
An enantioselective C-H arylation of phosphine oxides with o-quinone diazides catalyzed by an iridium(III) complex bearing an atropchiral cyclopentadienyl (Cp-x) ligand and phthaloyl tert-leucine as co-catalyst is reported. The method allows access to a) P ...
2018Cooperative Effects between Chiral Cp-x-Iridium(III) Catalysts and Chiral Carboxylic Acids in Enantioselective C-H Amidations of Phosphine Oxides
Nicolai Cramer, Yun-Suk Jang, Michael Christian Dieckmann
An enantioselective C-H amidation of phosphine oxides by using an iridium(III) catalyst bearing an atropchiral cyclopentadienyl (Cp-x) ligand is reported. A very strong cooperative effect between the chiral Cp-x ligand and a phthaloyl tert-leucine enabled ...
Wiley-Blackwell2017Metal Phosphorus Complexes as Antitumor Agents
Paul Joseph Dyson, Alexey Nazarov
Phosphorus-based ligands are an extremely important class of ligand and they have found many applications, especially in homogeneous catalysis. In addition, a phosphine ligand is found in a gold drug used to treat rheumatoid arthritis. Since metal compound ...
Springer Netherlands2011Influence of water-soluble sulfonated phosphine ligands on ruthenium catalyzed generation of hydrogen from formic acid
Paul Joseph Dyson, Gabor Laurenczy, Céline Fellay, Weijia Gan
Hydrogen can be generated from formic acid in aq. phase homogeneous catalytic reactions using ruthenium catalysts with water-sol. phosphine ligands. A comparison of tri-, di-, and mono-sulfonato triphenylphosphine, disulfonato diphenyl-alkyl-phosphines (Ph ...
Taylor & Francis2010Synthesis and anticancer activity of chalcogenide derivatives and platinum(II) and palladium(II) complexes derived from a polar ferrocene phosphanyl-carboxamide
Paul Joseph Dyson, Anna Katherine Renfrew
The polar phosphinyl carboxamide, 1'-(diphenylphosphino)-1-[N-(2-hydroxyethyl)carbamoyl]ferrocene [I; Z = null; (1)] , reacts readily with H2O2 and elemental S to give the corresponding phosphine oxide I [Z = O (2)] and phosphine sulfide I [Z = S (3)], res ...
Wiley-Blackwell2010Chiral Bronsted Acid-Catalyzed Enantioselective Three-Component Povarov Reaction
The three-component Povarov reaction of aldehydes, anilines, and benzyl N-vinylcarbamate in the presence of 0.1 equiv of chiral phosphoric acid afforded cis-2,4-disubstituted tetrahydroquinolines, e.g. I, in good yields and excellent enantiomeric excesses. ...
