Structural characterisation of solution species implicated in the palladium-catalysed Heck reaction by Pd K-edge X-ray absorption spectroscopy: palladium acetate as a catalyst precursor
Autor: John Evans, Thomas Neisius, Anthony R. J. Genge, Vijaya L. Kambhampati, Andrew J. Dent, Graham Rayner, Lynn O'Neill, Sandra Turin
Publikováno v: Journal of the Chemical Society, Dalton Transactions. :2207-2212
Energy dispersive EXAFS (EDE), Quick EXAFS (QEXAFS), 13C NMR and X-ray crystallography have been used to probe the co-ordination sphere of palladium in the course of the phosphine free Heck reaction. [Pd2I6][NBu3H]2 has been isolated from the precata

Simultaneous Determination of Structural and Kinetic Parameters Characterizing the Interconversion of Highly Dispersed Species: the Interaction of NO with RhI(CO)2/γ-Al2O3
Autor: Sakura Pascarelli, Sofia Diaz-Moreno, John Evans, Andrew J. Dent, Sandra Turin, Mark A. Newton, Daryl G. Burnaby, Thomas Neisius, Steven G. Fiddy
Publikováno v: The Journal of Physical Chemistry A. 105:5965-5970
Energy-dispersive EXAFS (EDE), combined with mass spectrometry and a flow microreactor system, has been used to investigate the reaction of an Al2O3-supported Rh-I(CO)(2) species with NO. This combined in situ approach uniquely permits a priori analy

Susceptibility of a heterogeneous catalyst, Rh/gamma-alumina, to rapid structural change by exposure to NO
Autor: Tom, Campbell, Andrew J, Dent, Sofia, Diaz-Moreno, John, Evans, Steven G, Fiddy, Mark A, Newton, Sandra, Turin
Publikováno v: Chemical communications (Cambridge, England). (4)
Metal particles in a Rh/gamma-Al2O3 catalyst of differing particle size are oxidised by NO/He within 5 seconds at 313 K; rapid, highly exothermic dissociative chemisorption of NO is the initial step.
