Base-Free Dynamic Kinetic Resolution of Secondary Alcohols Using “Piano-Stool” Complexes of N-Heterocyclic Carbenes
Marr, Andrew C.; Pollock, Ciara L.; Saunders, Graham C. (American Chemical Society, 2007)“Piano-stool” complexes of rhodium and iridium activated by fluorinated and non-fluorinated N-heterocyclic carbene (NHC) ligands were shown to be catalysts for racemization in the one-pot chemoenzymic dynamic kinetic ... -
Complexes of η⁵, κP-cyclopentadienyl-phosphine ligands by chelate-assisted dehydrofluorinative coupling; the coupling of bis{bis(pentafluorophenyl)phosphino}methane to η⁵-pentamethylcyclopentadienyl in a rhodium complex
Marr, Andrew C.; Nieuwenhuyzen, Mark; Pollock, Ciara L.; Saunders, Graham C. (Elsevier, 2006)The reaction between [{(η⁵-C₅Me₅)RhCl(μ-Cl)}₂] and (C₆F₅)₂PCH₂P(C₆F₅)₂ in refluxing benzene yields the singly linked complex [{(η⁵,κP-C₅Me₄ CH₂C₆F₄-2-P(C₆F₅)CH₂P(C₆F₅)₂)}RhCl₂] in which only one phosphorus atom is coordinated ... -
Minimizing side reactions in chemoenzymatic dynamic kinetic resolution: organometallic and material strategies
Pollock, Ciara L.; Fox, Kevin J.; Lacroix, Sophie D.; McDonagh, James; Marr, Patricia C.; Nethercott, Alanna M.; Pennycook, Annie; Qian, Shimeng; Robinson, Linda; Saunders, Graham C.; Marr, Andrew C. (Royal Society of Chemistry, 2012)Chemoenzymatic dynamic kinetic resolution (DKR) of rac-1-phenyl ethanol into R-1-phenylethanol acetate was investigated with emphasis on the minimization of side reactions. The organometallic hydrogen transfer (racemization) ... -
Review: Fluoroarylphosphines as ligands
Pollock, Ciara L.; Saunders, Graham C.; Smyth, E.C.M. Sarah; Sorokin, Vladimir I. (2008)This short review concentrates on important aspects of fluoroarylphosphines, in particular their synthesis, ligand properties and chemical and catalytic properties of their complexes. Although the electronic, steric and ... -
Synthesis of Piano Stool Complexes Employing the Pentafluorophenyl-Substituted Diphosphine (C₆F₅)₂PCH₂P(C₆F₅)₂ and the Effect of Phosphine Modifiers on Hydrogen Transfer Catalysis
Marr, Andrew C.; Nieuwenhuyzen, Mark; Pollock, Ciara L.; Saunders, Graham C. (American Chemical Society, 2007)Ruthenium, rhodium, and iridium piano stool complexes of the pentafluorophenyl-substituted diphosphine (C₆F₅)₂PCH₂P(C₆F₅)₂ (2) have been prepared and structurally characterized by single-crystal X-ray diffraction. The ...
