Carbonylation of Cyclotrisilenes
Angewandte Chemie International Edition, 2013Carbon monoxide (CO) is a common ligand in transitionmetal chemistry. In organic chemistry, it is frequently used to introduce a C1 unit, although carbonylations, such as hydroformylation or the Pauson–Khand reaction, generally require a transition-metal catalyst, even for strained (and thus highly reactive) cyclic compounds.

1,4-Carbonyl-carbonyl interactions
Experientia, 1960Es wird gezeigt, dass die IR-Spektren gewisser 1,4-Diketone und 1,4-Ketoester abnorm hohe Carbonylfrequenzen aufweisen, was auf das Vorhandensein eines intramolekularen Feldeffekts zwischen den beiden Carbonylgruppen in diesen Verbindungen hindeutet. Die ungewohnlichen Stabilitatsverhaltnisse an C-20 der 16,22-Dicarbonyl-Steroide sind vermutlich auf ...

Chemico-Biological Interactions, 2000
Carbonyl reductase (secondary-alcohol:NADP(+) oxidoreductase, EC 1.1. 1.184) belongs to the family of short chain dehydrogenases/reductases (SDR). Carbonyl reductases (CBRs) are NADPH-dependent, mostly monomeric, cytosolic enzymes with broad substrate specificity for many endogenous and xenobiotic carbonyl compounds.

Carbonyl polyhedra in crystalline carbonyl clusters
Transition Metal Chemistry, 1992An attempt has been made to elucidate the low-energy modes of vibration of the icosahedral envelope of carbonyl ligands in the series of dodecacarbonyl clusters, Co4(CO)12, RhCo2(CO)12, Ir2Co2(CO)12, and Fe3(CO)12, from an examination of their crystalline structures. It was hoped that this approach would give additional evidence necessary for a clearer

Detoxification of Carbonyl Compounds by Carbonyl Reductase in Neurodegeneration
2016Oxidative stress in the brain is the major cause of neurodegenerative disorders, including Alzheimer's, Parkinson's, Huntington's, and Creutzfeldt-Jakob diseases or amyotrophic lateral sclerosis. Under conditions of oxidative stress, the production of highly reactive oxygen species (ROS) overwhelms antioxidant defenses, resulting in the modification of

Science, 1941
When the metal carbonyls were first discovered, their properties were startling because they seemed to violate nearly all the previously recognized generalizations of chemistry. Even to-day the existence of the carbonyls is not particularly emphasized in elementary courses of chemistry because it is rather hard to reconcile them with the first ...

Binuclear Cyclopentadienylcobalt Carbonyls: Comparison with Binuclear Iron Carbonyls
Journal of the American Chemical Society, 2005The binuclear cyclopentadienylcobalt carbonyls Cp2Co2(CO)n (n = 3, 2, 1; Cp = eta5-C5H5) are studied by density functional theory using the B3LYP and BP86 functionals. The experimentally known monobridged isomer Cp2Co2(CO)2(mu-CO) and the tribridged isomer Cp2Co2(mu-CO)3 of Cp2Co2(CO)3 with formal Co-Co single bonds are found to be similar in energy ...

Darmstadtium carbonyl and carbide resemble platinum carbonyl and carbide
Chem. Commun., 2004DsC and DsCO are calculated to be very similar to PtC and PtCO, suggesting that even the latest 6d elements resemble the corresponding 5d elements chemically.
