Machine learning has recently been introduced into the arsenal of tools that are available to computational chemists.

An attractive application machine electronic structure theory is "recycling" wave functions for faster more accurate completion complex quantum calculations. Along lines, developed hybrid chemical/machine workflows utilize information from low-level prediction higher-level functions. The data-driven coupled-cluster (DDCC) family methods discussed this article together with importance inclusion physical properties such workflows. After short introduction philosophy capabilities DDCC, present our recent progress extending its larger structures data sets. A significant advantage offered by DDCC transferability, respect different systems excitation levels. As show here, predicted at singles doubles level can be used perturbative triples CCSD(T) scheme. We conclude some personal considerations future directions related development next generation models.

This study investigates the Cope elimination reaction, focusing on mechanistic shift between concerted and stepwise pathways influenced by substituent effects. Experimental approaches, including kinetic isotope effects (KIEs) linear free energy relationships (LFERs), alongside density functional theory (DFT) computations, were employed to explore influence of substituents reaction kinetics pathways. Our findings reveal temperature- substituent-dependent partitioning syn-β E1cB mechanism, providing deeper insights into diversity reactions.

Enantioselective C(sp3)-H bond oxidation is a powerful strategy for installing functionality in rich molecules. Site- and enantioselective of strong C-H bonds monosubstituted cyclohexanes with hydrogen peroxide catalyzed by aminopyridine manganese catalysts combination alkanoic acids has been recently described. Mechanistic uncertainties nonobvious enantioselectivity trends challenge development the full potential this reaction as synthetic tool. Herein, we apply predictive statistical analysis to identify mechanistically informative correlations that provide valuable understanding will guide future optimization reactions.
