In situ generation of Mes2Mg as a non-nucleophilic carbon-centred base reagent for the efficient one-pot conversion of ketones to silyl enol ethers [PDF]

open access: yes, 2008
Treatment of commercially available MesMgBr with 1,4-dioxane produces the key Mes2Mg reagent in situ which then mediates the deprotonation of ketones to deliver trimethylsilyl enol ethers, at readily accessible temperatures and without any nucleophilic ...

Organometallic and Bioorganometallic Chemistry - Ferrocene and Metal Carbonyls [PDF]

open access: yesKemija u Industriji, 2011
Organometallic chemistry deals with compounds containing metal-carbon bonds. Basic organometallics derived from the s- and p-block metals (containing solely σ-bonds) were understood earlier, while organometallic chemistry of the d- and f-block has ...

Fundamental organometallic reactions: Applications on the CYBER 205 [PDF]

open access: yes, 1984
Two of the most challenging problems of Organometallic chemistry (loosely defined) are pollution control with the large space velocities needed and nitrogen fixation, a process so capably done by nature and so relatively poorly done by man (industry ...

Formation and characterization of inorganic membranes from zeolite-silica microcomposites [PDF]

open access: yes, 1988
Small crystals of zeolites (500-1000 nm) with two- and three-dimensional channel systems (faujasite and ZSM-5 structures) were embedded in amorphous thin films derived from TEOS hydrolyzed in alcoholic solution.

Hydrodenitrogenation of pyridines and quinolines at a multinuclear titanium hydride framework

open access: yesNature Communications, 2017
Hydrodenitrogenation is a fundamental process in the petroleum refinery context. Here, the authors report the mild ring-opening and denitrogenation of pyridines and quinolines with a titanium hydride cluster and the unusual formation of denitrogenated ...

Sensitivity of the photo-physical properties of organometallic complexes to small chemical changes

open access: yes, 2010
We investigate an effective model Hamiltonian for organometallic complexes that are widely used in optoelectronic devices. The two most important parameters in the model are $J$, the effective exchange interaction between the $\pi$ and $\pi^*$ orbitals ...

A SaBOX/Co catalyst designed for facile access to the challenging copolymers of vinyl ester and methacrylate

open access: yesNature Communications
Copolymerization of more activated methacrylates and less activated vinyl esters is challenging because of their large difference in reactivity ratio. This severely limits the development of high-performance materials.

Bismuth Porphyrin Antagonizes Cisplatin-Induced Nephrotoxicity via Unexpected Metallothionein-Independent Mechanisms

open access: yesiScience, 2020
Summary: Cisplatin (CDDP) has been a highly successful anticancer drug in cancer therapy; however, its further application suffers severe nephrotoxicity.
