Autor: James A. S. Howell, John C. Kola, Denis T. Dixon
Publikováno v: Journal of Organometallic Chemistry. 266:69-82
(η4-enone)Fe(CO)2L complexes (enone = benzylideneacetone, cinnamaldehyde; L = PPh3-xMex (x = 0–2), P(OPh)3) exist as interconverting isomeric mixtures in solution in which L occupies either the axial or basal position of a square pyramidal structu

The mechanism of displacement of diene from [M(η4-diene)(CO)4](M = Cr, Mo, or W, diene = norbornadiene; M = Mo, diene = cyclo-octa-1,5-diene) and the cis⇌trans isomerization of [M(CO)4L2] complexes [L = PBu3, P(OMe)3, or P(OPh)3]
Autor: James A. S. Howell, Denis T. Dixon, John C. Kola
Publikováno v: J. Chem. Soc., Dalton Trans.. :1307-1315
Kinetic studies are reported of the displacement of the diene from [M(η4-diene)(CO)4][diene = norbornadiene, M = Cr, Mo, or W; diene = cyclo-octa-1,5-diene (cod), M = Mo] by phosphorus ligands [L = PBu3, P(OMe)3, or P(OPh)3] to give complexes [M(CO)

A kinetic investigation of arene exchange and substitution in (naphthalene)Cr(CO)3
Autor: Neil F. Ashford, Denis T. Dixon, James A. S. Howell, John C. Kola
Publikováno v: Journal of Organometallic Chemistry. 294:c1-c4
The rate of (naphthalene)Cr(CO) 3 with toluene in n-nonane to give (toluene)Cr(CO) 3 is independent of the toluene concentration, whereas the rate of substitution by P(OMe) 3 to give fac -Cr(CO) 3 [P(OMe) 3 ] 3 is first order with respect to the conc

Excess Gibbs function for a binary mixture obtained from dew point and bubble point pressure measurements
Autor: Denis T. Dixon, F. Anthony Hewitt
Publikováno v: Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases. 75:1940
This paper describes a method by which the excess Gibbs function for a binary mixture may be obtained from dew point and bubble point pressure measurements, without any need for accurate measurement of composition. Details of an apparatus suitable fo

Kinetics and mechanism of mono- and di-olefin exchange at five-co-ordinate iron(0)
Autor: Denis T. Dixon, Philip M. Burkinshaw, James A. S. Howell
Publikováno v: Journal of the Chemical Society, Dalton Transactions. :999
Exchange of various mono-olefins with styrene in [Fe(CO)4(PhCHCH2)] proceeds via a dissociative process, involving an Fe(CO)4 intermediate. Ligand exchange in system (i)(enone = benzylideneacetone, cinnamaldehyde, chalcone, or dypnone; polyene = cycl
