Use of mixed Li/K metal TMP amide (LiNK chemistry) for the synthesis of [2.2]metacyclophanes

Beilstein Journal of Organic Chemistry, 2011
A new two-step general approach to [2.2]metacyclophane synthesis from substituted m-xylenes is described. The strategy employs a selective benzylic metalation and oxidative C–C bond formation for both synthetic operations.

Metalation Studies on Titanocene Dithiolates

Inorganics, 2018
Titanocene bis-arylthiolates [(C5H4X)(C5H4Y)Ti(SC6H4R)2] (X,Y = H, Cl; R = H, Me) can be prepared from the corresponding titanocene dichlorides by reacting with the thiols in the presence of DABCO as a base.

Skeletal metalation of lactams through a carbonyl-to-nickel-exchange logic

Nature Communications, 2023
Classical metalation reactions such as the metal-halogen exchange have had a transformative impact on organic synthesis owing to their broad applicability in building carbon-carbon bonds from carbon-halogen bonds.

Cationic Protic Imidazolylidene NHC Complexes of Cp*IrCl+ and Cp*RhCl+ with a Pyridyl Tether Formed at Ambient Temperature

Inorganics, 2018
Protic NHC (PNHC) complexes with N1H, N2-alkyl/aryl imidazolylidene ligands are relatively rare, and routes for their synthesis differ from what is used to make non-protic analogs.

Organometallic Chemistry within the Structured Environment Provided by the Macrocyclic Cores of Carbaporphyrins and Related Systems

Molecules, 2023
The unique environment within the core of carbaporphyrinoid systems provides a platform to explore unusual organometallic chemistry. The ability of these structures to form stable organometallic derivatives was first demonstrated for N-confused ...

Protein metalation in biology

, 2022
Inorganic metals supplement the chemical repertoire of organic molecules, especially proteins. This requires the correct metals to associate with proteins at metalation. Protein mismetalation typically occurs when excesses of unbound metals compete for a

Metal Metal

Artilugio, 2023
METAL METAL es una pieza electroacústica creada en 2022. El material sonoro utilizado en la composición fue grabado durante la pandemia mundial de Covid-19. Aprovechando el aislamiento obligatorio, se realizaron sesiones de improvisación rítmica, tímbrica y textural con latas de aluminio. Estas se registraron con un grabador digital Zoom H4.

Kinetic Versus Thermodynamic Metalation Enables Synthesis of Isostructural Homo- and Heterometallic Trinuclear Clusters

, 2020
Temperature-dependent metalation of the new hexadentate ligand (tris(5-(pyridin-2-yl)-1H-pyrrol-2-yl)methane; H3TPM) enables the selective synthesis of both mononuclear (i.e. Na(THF)4[Fe(TPM)], kinetic product) and trinuclear (i.e.

Synthesis of Phenacene−Helicene Hybrids by Directed Remote Metalation [PDF]

, 2020
Polycyclic aromatic hydrocarbons (PAHs) with six and seven rings were synthesized via directed metalation and cross-coupling of chrysenyl N,N-diethyl carboxamides with o-tolyl and methylnaphthalenyl derivatives.

TerC proteins function during protein secretion to metalate exoenzymes

Nature Communications, 2023
Cytosolic metalloenzymes acquire metals from buffered intracellular pools. How exported metalloenzymes are appropriately metalated is less clear. We provide evidence that TerC family proteins function in metalation of enzymes during export through the ...
