Amphiphilic Biaryl Monophosphine Ligands by Regioselective Sulfonation

<div> <p>Amphiphilic ligands are valued for their ability to facilitate organometallic reactions in the presence of water. The regioselective sulfonation of a series of commercially available biaryl monophosphines to generate amphiphilic ligands is presented. In this one-step protocol, the temperature and addition of fuming sulfuric acid were carefully controlled to arrive at sulfonated biaryl monophosphine ligands in high yields with >95% regioselectivity without the need for chromatographic purification.</p> </div>

autodE: Automated Calculation of Reaction Energy Profiles – Application to Organic and Organometallic Reactions

Calculating reaction profiles to aid in mechanistic elucidation has long been the domain of the expert computational chemist. We introduce autodE, an open-source tool capable of locating transition states and minima and delivering a full reaction energy profile with minimal human effort (https://github.com/duartegroup/autodE). autodE is broadly applicable to study organic and organometallic reaction classes, including addition, substitution, elimination, migratory insertion, oxidative addition and reductive elimination; it accounts for conformational sampling of both minima and TSs, and is compatible with many electronic structure packages. The general applicability of autodE is demonstrated in complex multi-step reactions, including metal-catalyzed cobalt- and rhodium-catalyzed hydroformylation, and an Ireland-Claisen rearrangement.
