Bipyridine Ligands for use in Polymer-Supported Iridium Catalyzed C-H Borylation
… has shown high recyclability of precious metal catalysts. This project explored several synthetic routes to make a polymer-support linker to use in organic synthesis. Bipyridine ligands, such as 4, 4’-tert-butyl-bipyrine with an iridium precatalyst afford a highly efficient C-H borylation, but …

On the design and further applications of iridium (I) complexes in hydrogen isotope exchange processes
… for isolation of three established Kerr group catalysts has been successfully developed. The final yield of these catalysts has now been improved beyond those published in the literature, and has allowed for the commercialisation of such catalysts for the first time. The synthesis of a series …

Iridium Complexes for Intracellular Transfer Hydrogenation and Their Potential Biological Applications
… small-molecule intracellular metal catalysts (SIMCats) that are capable of catalyzing such reactions inside living systems have recently been discovered by our research group and others. We found that pentamethylcyclopentadienyl iridium(III) (Cp*Ir) complexes bearing …

Change Of Metal Oxidation State At High Temperature, Impact Of Temperature And Reactive Gases
… catalysis, the use of metal doped heterogeneous catalysts are essential in achieving selectivity and conversion performance for chemical synthesis to emissions abatement. Typically, these metal alloys must withstand temperatures up to 1000 °C at pressures near 30 bar continuously for 8000 hours …

A hydrogen bonding ortho-directing effect for the iridium catalyzed borylation of NH(t-BOC) aromatics
… and others act as steric obstacles for the iridium catalyst to avoid. This avoidance of appending groups can be reversed into a directed borylation with monophosphine ligands. Alternatively, the SiMe2H group elicits an ortho-directing effect via oxidative addition to the metal center. …

Cobalt catalysts towards parahydrogen induced polarization
… has been used in conjunction with rhodium and iridium homogeneous catalysts in the field of Parahydrogen Induced Polarization (PHIP) to yield large signal enhancements over the standard signals traditionally achieved in MRI and NMR spectroscopy. This field has advanced to yield enhancements via …
