Double hybrids especially excel in thermochemistry, kinetics, transition metal chemistry, and the description of strained organic systems. They often provide improvements over the best performing, dispersion-corrected hybrid functionals. With the recent efficient MP2 implementation in...
The automation of workflows in computational chemistry becomes increasingly more important. The tool PyFrag 2019 of the Amsterdam Modeling Suite is an example for this.[1,2] PyFrag automates the individual computational steps needed to perform an in-depth...
In a recent experimental and computational study a group of researchers from the University of Saarbrücken, Germany, investigated the structure and chemical bonding of tin(II) halide and hal-sandwich complexes with cyclic (alkyl)(amino)carbenes (cAACs). Compared to...
Whether you are a solid state physicist thinking of chemistry as too arcane or a chemist puzzled by band structure theory: Try out our new tutorial and learn how to neatly link these two fields,...
In a recent Science paper the Gaunt group reports facile access to β-lactams via palladium-catalyzed coupling of aliphatic amines and carbon monoxide. The scope of the reaction is remarkably broad; over 40 substrates are illustrated, bearing a...
A spin forbidden reaction occurs with a change of the total electronic spin from reactants to products. The mechanistic study is therefore not trivial, since the reaction does not occur on a single adiabatic potential...
In a recent study, the interaction of various methylaluminoxane (MAO) models on the (110) MgCl2 surface were studied with dispersion corrected DFT (revPBE-D3) in ADF. MAO activates the metallocene catalyst, but the structure(s) of MAO are...
Homogeneous gold catalysis has reached an extraordinary level of popularity within organic synthesis as a fundamental tool in the nucleophilic reactions of isolated π-systems, C-H activation, cross-couplings, photocatalysis and enantioselective transformations. Together with the ligand...
X-ray spectroscopy has become a commonly used tool to probe to structure of transition metal complexes, allowing for element-specific measurements. Conventional X-ray absorption spectroscopy (XAS) masurement transmission like UV-Vis, however this methodology is subject to...
Oxidative addition and reductive elimination reactions of small molecules possessing high-order bonds (e.g. N2, O2, NO+) is of fundamental interest in transition metal chemistry. As a means to study the mechanism and intermediates of such...
