De novo prediction of the ground state structure of transition metal complexes.
… reasonable geometries for target materials. Organometallic complexes have been investigated in this dissertation research, entailing a significant challenge based on transition metal diversity and the associated complexity of the ligands. A large variety of theoretical methods have been …

Total Synthesis of the 2-Nitropyrrole Natural Product Heronapyrrole C
… a vinylation of iodide 299 with a suitable vinyl organometallic species (300). The iodide coupling partner 299 was successfully synthesised from 2-nitropyrrole 144. A successful model reaction between iodide 299 and vinyltributyltin indicated the viability of the vinylation strategy, however, the …

Organometallic redox-interfaces for selective electrochemical separations
… excess of competing electrolyte. In particular, organometallics and associated metalcomplexes offer an attractive material platform, due to their flexible metal-ligand design and as a consequence, extensive control allowed of their electronic properties. The first major thrust is the molecular …

Synthesis, characterization and reactivity of Group 6 alkoxo nitrosyl complexes
… alkyl complexes decompose cleanly to isolable organometallic species when treated with 02 or H2O. In Lewis acid-base type reactions with PMe3, CNCMe3, PhNCO and p-tolylNCO, the Cp*M(N0)(R)(OR') species have sufficiently electron-deficient metal centers to form 1:1 adducts and/or insertion …

Photoredox activation of SF₆ for fluorination, on-demand automated titration of organometallic reagents in continuous flow, and progress toward an enantioselective synthesis of bedaquiline
… SF6, an inert gas, into an active fluorinating species using visible light and photoredox catalysis. Under these conditions, deoxyfluorination of allylic alcohols is affected with high chemoselectivity and is tolerant of a wide range of functional groups. Application of the methodology in a …

Nitric oxide reactions of bio-Inspired zinc and cobalt complexes
… their reactivity toward reactive nitrogen species. This type of chemistry is proposed to occur at the zinc tetracysteine thiolate site of nitric oxide synthase (NOS). The complexes are unreactive toward nitric oxide in the absence of dioxygen, strongly indicating that NO cannot be the …

Engineering site-isolated reactive metal complexes within a Metal-organic Framework
… the opportunity to structurally characterize organometallic species isolated within MOF architectures and explore the potential of these unique systems for application in commercially attractive processes. The Mn-based MOF ([Mn₃L₂L’)] where L = …

Solid Phase Synthesis and Biological studies on metal conjugates of bioactive peptides for targeted delivery
… these bioconjugates and the NLS transports the organometallic species into the nuclei. This is the first example of the directed nuclear delivery of ferrocene and the cobaltocenium cation, by conjugation to the NLS peptide. The use of the scrambled NLS sequence (NLSscr) abolishes the nuclear …

Chloroform as a carbon monoxide precursor: in or ex situ generation of co for pd-catalyzed carbonylations IV. Hydroalkylation of alkenes via photoredox catalysis
… a photocatalyst has been achieved. Soft organometallic species and carboxylic acids serve as shelf-stable alkyl fragments and can be appended to vinylarenes through a radical mechanism. The functional group tolerance of this reaction is excellent, owing to very mild conditions. …
