A ruthenium meso-tetra[4-(vinylbenzoxy)benzyl]porphyrin catalyst with four meso-polymerizable side chains was synthesized in three steps from commercially available starting materials. The polymerizable side chains allowed the incorporation of this complex ...
The phosphido-substituted triruthenium cluster Ru-3(CO)(9)(mu-H)(mu-PPh2) is shown to react with H-2 to form the trihydride cluster Ru-3(CO)(9)(H)(mu-H)(2)(mu-PPh2), which undergoes a number of re-arrangement reactions on heating to yield other phosphido-s ...
This paper focuses on the mechanism by which a monoterpene undergoes a cyclocarbonylation reaction catalysed by a palladium complex. Evidence is provided, based on intermediate species observed under pressure or with various ligands, that the catalytic cyc ...
The relation between the catalyst potential and the catalytic performance has been investigated in the gas-phase combustion of propylene with oxygen over rhodium catalysts at 375 DegC. The rhodium catalyst, deposited on yttria-stabilized zirconia (YSZ) sol ...

The basic aqueous coordination chemistry of Ru-II has been studied using the catalytically important TPPTS phosphine (TPPTS = trisodium salt of 3,3 ',3 ''-phosphinetriylbenzenesulfonic acid) and small gas molecules (H-2, CO, N-2) as ligands. As a result, n ...
High-pressure NMR mechanistic investigations into the promoting role of dicarbonyldiiodoplatinum complex in the iridium-catalysed carbonylation of methanol to acetic acid are consistent with iodide abstraction from the [IrI3(CH3)(CO)2]– resting state speci ...
The diphosphane-substituted clusters [Ru-3(CO)(10)(dppe)] and [Ru-3(CO)(8)(dppe)(2)] [dppe = 1,2-bis(diphenylphosphanyl)ethane] are shown to catalytically hydrogenate diphenylacetylene. This process is highly solvent-dependent with fragmentation dominating ...
Catalysts immobilised in ionic liquids have been analysed using electrospray ionisation ion trap mass spectrometry, which allows identification of the catalyst without contamination from the ionic liquid; additionally, a new ionic liquid containing the Mon ...
