Predicting Reaction Feasibility and Selectivity of Aromatic C–H Thianthrenation with a QM-ML Hybrid Approach
The direct thianthrenation of aromatic C–H bonds is a valuable late-stage functionalization strategy that can assist, for example, the development of new drugs. We herein present a predictive computat...

Computational tools for the prediction of site- and regioselectivity of organic reactions
The regio- and site-selectivity of organic reactions is one of the most important aspects when it comes to synthesis planning. Due to that, massive research efforts were invested into computational mo...

Mechanistic Study of Photochemical Aminocarbonylation of Alkyl Iodides Catalyzed by a Palladium Catalyst Using Experimental and Computational Methods
Aminocarbonylations are versatile reactions amenable to applications in convergent synthesis and isotope labeling. Herein, a mechanistic study of a previously reported visible-light-promoted aminocarbonylation of unactivated alkyl iodides is presented. This study combines in situ spectroscopy, computational chemistry, and organic chemistry techniques. A T1 excited-state promoted ligand dissociation in concert with an atom transfer radical addition was uncovered as a likely first step in the mechanism, instead of the usual three-center oxidative addition. Improvement in the reaction yield was achieved by optimizing the reaction based on mechanistic insights. This took the form of promoting a computationally uncovered cationic carbonylation pathway with the use of bidentate ligands.
