  • Backbone tuning in indenylidene-ruthenium complexes bearing an unsaturated N-heterocyclic carbene 

    Urbina-Blanco, Cesar A.; Bantreil, Xavier; Clavier, Herve; Slawin, Alexandra M. Z.; Nolan, Steven P. (2010-11) - Journal article
    The steric and electronic influence of backbone substitution in IMes-based (IMes = 1,3-bis(2,4,6-trimethylphenyl)imidazol-2-ylidene) N-heterocyclic carbenes (NHC) was probed by synthesizing the [RhCl(CO)(2)(NHC)] series ...
  • Copper-NHC complexes in catalysis 

    Lazreg, Faima; Nahra, Fady; Cazin, Catherine S.J. (2015-06-15) - Journal article
    Although the chemistry of copper has a long history [1a-d], the relatively recent discovery of N-heterocyclic carbene (NHC) as transition-metal supporting ligands has permitted novel vistas to be explored in copper reactivity ...
  • Gold-acetonyl complexes : from side-products to valuable synthons 

    Gasperini, Danila; Collado-Martinez, Alba; Gomez Suarez, Adrian; Cordes, David Bradford; Slawin, Alexandra Martha Zoya; Nolan, Steven Patrick (2015-03-27) - Journal article
    A new synthetic strategy was devised leading to the formation of complexes, such as [Au(IPr)(CH2COCH3)]. The approach capitalizes on the formation of a decomposition product observed in the course of the synthesis of ...
  • Group 11 N-heterocyclic carbenes : synthesis, characterisation and catalytic applications 

    Lazreg, Faïma (University of St Andrews, 2015-06-24) - Thesis
    As part of a worldwide effort to develop efficient catalysts for use in organic chemistry and in the synthesis of highly valuable molecules, work performed during the course of my stay in St Andrews has focused on the ...
  • [Pd(NHC)(PR3)] complexes : versatile tools for tandem dehydrogenation-hydrogenation processes 

    Songis, Olivier; Cazin, Catherine S.J. (2013-09-17) - Journal article
    Homogeneous Pd(0) complexes are powerful tools for numerous catalytic reactions. Recent work has demonstrated the unique properties displayed by [Pd(NHC)(PR3)] catalysts in the activation of ammonia borane (AB) and formic ...
  • Proton transfer reactions of N-aryl triazolium salts : unusual ortho-substituent effects 

    Tucker, David E.; Quinn, Peter; Massey, Richard S.; Collett, Christopher John; Jasiewicz, David J.; Bramley, Christopher R.; Smith, Andrew David; O’Donoghue, AnnMarie C. (2015-02) - Journal article
    Previous studies of the C(3)-hydrogen/deuterium exchange reactions of the triazolium ion conjugate acids of triazolyl N-heterocyclic carbenes revealed a change of mechanism under acidic conditions with N1-protonation to a ...
  • The role of silver additives in gold-mediated C-H functionalisation 

    Patrick, Scott R.; Boogaerts, Ine I. F.; Gaillard, Sylvain; Slawin, Alexandra M. Z.; Nolan, Steven P. (2011-07-01) - Journal article
    The role of silver additives is examined in the context of gold-mediated functionalisation of aromatic C-H bonds. Doubt is cast on the commonly cited route of halide abstraction from gold and evidence of substrate activation ...
