Alkyl isomerisation in three-coordinate iron(II) complexes.
The tertiary to iso-butyl isomerisation of three-coordinate iron(II) diketiminate complexes is reported and a hydride intermediate is proposed on the basis of exchange experiments.
متن کاملA biocatalytic redox isomerisation.
A bi-enzymatic cascade for the redox-isomerisation of allylic alcohol is presented. Coupling of an alcohol dehydrogenase to an enoate reductase has been successfully applied in one pot for the isomerisation of an allylic alcohol to the corresponding ketone. Critical parameters for yield and selectivity have been investigated.
متن کاملExopolyhedral ligand flipping on isomerisation of novel supraicosahedral stannacarboranes.
Novel p-block metallacarboranes with 4,1,10-SnC2B10 and 4,1,12-SnC2B10 architectures are described; the structures of bipyridyl adducts of these compounds reveal very different bipyridyl orientations yielding unique experimental information on the relative trans influences of facial B and C atoms in the cage.
متن کاملForming a ruthenium isomerisation catalyst from Grubbs II: a DFT study.
A DFT investigation into the mechanism for the decomposition of Grubbs 2nd generation pre-catalyst (2) in the presence of methanol, is presented. Gibbs free energy profiles for decomposition of the pre-catalyst (2) via two possible mechanisms were computed. We predict that decomposition following tricyclohexylphosphane dissociation is most favoured compared to direct decomposition of the pre-ca...
متن کاملPhoto-isomerisation of alkenyl complexes of platinum(II): structural, spectroscopic, kinetic and computational investigations.
In this work UVA and blue light have been used to study photo-isomerisation about the C=C double bond in complexes of the type [PtCl(-CH=CHAr)(tmeda)] [Ar = C6H5, (E)-2a; 4-CH3O-C6H4, (E)-2b; 3-NO2-C6H4, (E)-2c; and 3-CH3O-C6H4, (E)-2d]. The progress of the reaction has been monitored by NMR spectroscopy following irradiation of the NMR sample. The NMR data have been complemented with X-ray dif...
