Germanium hydride derivatives of transition metal carbonyls
Compounds of the type Fe(CO)₄(GeR₃)₂ containing two different methylgermyl substituents have been prepared and characterised. The preparation was via the exchange reaction Fe(CO)₄(GeR₃)₂ + [Mn(CO)₅]⁻ → [Fe(CO)₄(GeR₃)]⁻ + Mn(CO)₅(GeR₃) [Fe(CO)₄(GeR₃)]⁻ + GeXR’₃ → Fe(CO)₄(GeR₃)(GeR’₃) The compounds …

Mass Spectroscopic Identification and Quantification of Protein Carbonyls
It is well established that free radical mediated oxidative stress plays a critical role in aging and age-related diseases. Among the post-translational protein modifications, carbonylation has attracted a great deal of attention due to its irreversible and irreparable nature. Despite the fact that …

Base Catalysis of Ligand Substitution in Metal Carbonyls
Manganese(I) carbonyls can undergo substitution by a variety of mechanisms. Three different mechanisms have been found for the substitution reactions of Mn(CO)(,5)CH(,3)CN('+).

The in situ synthesis of supported ruthenium carbonyls
The compound Ru⁺²(CO)₃Cl₂(THF) spontaneously adsorbs onto MgO, Al₂O₃, SiO₂, and NaY zeolite from THF solution evolving less than 0.1 equivalent of CO to yield a light yellow supported complex. Based on reaction stoichiometry, CO evolution and in situ infrared spectroscopy, the adsorption was found …

Multinuclear Solid-State NMR Studies of Supported Transition Metal Carbonyls
High field carbon-13 and oxygen-17 nuclear magnetic resonance (NMR) spectra have been obtained for a variety of transition metal carbonyl clusters, metal oxides, and oxide-supported metal carbonyl complexes. Magic-angle spinning (MAS) C-13 NMR spectra of polycrystalline metal carbonyl clusters …

Cyclopentadienyl ruthenium sulfide carbonyls and thiophene activation by iron and rhodium
The desulfurization and reduction of the sulfur-containing organic compounds in petroleum products is the objective of catalytic hydrodesulfurization (HDS), one of the largest applications of transition-metal catalysis. However, the specific mechanism for the process is not well understood. This …

Thermochemistry and bond energies of nitro -alkanes, -alkenes, -carbonyls and corresponding nitrites
Density functional and ab initio theory based calculations were performed on a series of nitro -alkanes, -alkenes, carbonyl and corresponding nitrites representing large-scale primary, secondary and tertiary nitro compounds and their radicals resulting from the loss of skeletal hydrogen atoms. …

Deposition of Metal Oxides and Metal Carbonyls on Silicon Surfaces Using Solution Chemistry
The Si-H bonds on the H-Si(111) surface and Co2(CO)8 in n-heptane solution reacted to form a well defined submonolayer coverage of Co(CO)4 above the surface plane of Si(111). Transmission Fourier-transform infrared spectroscopy analysis of (OC) 4Co-Si(111) yielded structural and geometric …

Primary Photoproducts and the Mechanism of Ligand Substitution in the Photochemistry of Dinuclear Metal Carbonyls
Flash photolysis methods were used to investigate the photochemistry of bis(pentamethylcyclopentadienylmolybdenumtricarbonyl). The results indicate that both metal-metal bond homolysis and CO loss occur as primary photoprocesses. Transient absorbances in the visible region were observed for both …

A study of carbonyl formation within an innovative indoor air pollution abatement system
… to qualitatively and quantitatively determine if carbonyls were formed in the airstream when the system was operated, and if so, to determine what factors affected the concentrations of these compounds. Trials were conducted using benzene and 2-butanol as challenge chemicals. A variety of test …
