The Interface of Hybridization, Hyperconjugation, and Conformation in Organic Chemistry Teaching Hybridization is a bonding model, universally used in organic chemistry, which allows consideration of two-electron localized bonds in organic molecules. Without hybridization, it is almost impossible...

Our thoughts on the teaching of hybridization and how it impacts hyperconjugation have just been published in J. Chem. Ed.

If you know organic chemists within the education sector, please share.

Thanks for the nice work 😃!

Maybe interesting for some here: AIMNet2 will also be available to be used together with the upcoming ORCA 6.1 (release next Tuesday 17/06) to run optimizations, conformational searches, NEB, etc.

Hopefully even more people will be able to try it.

Hydrogen-Bond-Assisted Chalcogen Transfer between Phosphine Selenides and Arsine Oxides The Brønsted acid catalysis is widely regarded as one of the most effective methods for activating inert substrates and enabling unique reactivity. In this work, we introduce the first example of H-bond-assisted chalcogen exchange between arsine oxides and phosphine selenides under mild conditions, providing a powerful approach to the synthesis of arsine selenides. The reaction proceeds successfully in both protic and aprotic solvents and is accelerated by the presence of any nonaqueous acid. This newly discovered reaction is tested for various arsine oxides R3AsO (R = Ph, Et, nBu, iPr) and phosphine selenides R3PSe (R = Ph, Me, Et, tBu) and overall demonstrates high conversion, although the use of reagents with bulky substituents significantly hinders its efficiency. The reaction mechanism involves the formation of a four-membered cyclic transition state, which requires overcoming steric and electrostatic repulsion, as well as significant distortion of the reagents’ tetrahedral geometry. Hydrogen bonding with the As═O fragment helps to reduce electrostatic repulsion between the P═Se and As═O groups, making the formation of the cyclic intermediate more favorable.

Check our new paper in @pubs.acs.org Inorganic Chemistry on how hydrogen bonding facilitates chalcogen exchange between arsine oxides and phosphine selenides.

GOAT: A Global Optimization Algorithm for Molecules and Atomic Clusters In this work, we propose a new Global Optimization Algorithm (GOAT) for molecules and clusters of atoms and show how it can find the global energy minima for both systems without resorting to molecul...

The Global Optimization Algorithm (🐐) paper is out on Angewandte Chemie.

In the following days, we will try to take some time to show more of what it can do. For now, you can find already many examples on the paper.

It is already fully available on ORCA6!
