Species sensitivity of zeolite minerals for uptake of mercury solutes [PDF]

open access: yes, 2006
The uptake of inorganic Hg2+ and organometallic CH3Hg+ from aqueous solutions by 11 different natural zeolites has been investigated using a batch distribution coefficient (Kd) method and supported by a preliminary voltammetric study.

Simulation of Heme using DFT+U: a step toward accurate spin-state energetics [PDF]

open access: yes, 2007
We investigate the DFT+U approach as a viable solution to describe the low-lying states of ligated and unligated iron heme complexes. Besides their central role in organometallic chemistry, these compounds represent a paradigmatic case where LDA, GGA ...

The Future of Polar Organometallic Chemistry Written in Bio-Based Solvents and Water.

open access: yesChemistry, 2018
There is a strong imperative to reduce the release of volatile organic compounds (VOCs) into the environment, and many efforts are currently being made to replace conventional hazardous VOCs in favour of safe, green and bio-renewable reaction media that ...

Palladium/N-heterocyclic carbene catalysed regio and diastereoselective reaction of ketones with allyl reagents via inner-sphere mechanism

open access: yesNature Communications, 2016
Palladium catalyzed allylic substitution reactions typically proceed via an outer sphere mechanism, yielding predominately linear products. Here, the authors report an inner sphere process for the allylic substitution of ketone enolates, giving branched ...

Catalisadores contendo carbenos n-heterocíclicos como ligantes: propriedades, sínteses, aplicações e comparação com outros ligantes Catalysts containing n-heterocyclic carbenes as ligands: properties, syntheses, applications and comparison with other catalysts

open access: yesQuímica Nova, 2008
N-heterocyclic carbenes (NHCs) have become of considerable importance in modern organometallic chemistry and homogeneous catalysis. There are several advantages in the use NHCs over their phosphorus analogues, which explains the enormous development of ...
