London dispersion constitutes one of the fundamental interaction forces between atoms and between molecules. While modern computational methods have been developed to describe the strength of dispersive interactions in the gas phase properly, the importance of inter-and intramolecular dispersion in solution remains yet to be fully understood because experimental data are still sparse in that regard. We herein report a detailed experimental and computational study of the contribution of London dispersion to the bond dissociation of proton-bound dimers, both in the gas phase and in dichloromethane solution, showing that attenuation of inter-and intramolecular dispersive interaction by solvent is large (about 70% in dichloromethane), but not complete, and that current state-of-The-Art implicit solvent models employed in quantum-mechanical computational studies treat London dispersion poorly, at least for this model system.

A redox neutral, highly enantioselective coupling between N-arylaminomethanes and N-sulfonyl aldimines was developed by harnessing the efficient catalysis of P-spiro chiral arylaminophosphonium barfate and a transition-metal photosensitizer under visible

This study describes a heteroligated, hemilabile PtII-P,S tweezer coordination complex that combines a chiral Jacobsen-Katsuki Mn III-salen epoxidation catalyst with an amidopyridine receptor, which leads to an inversion of the major epoxide product compared to catalysts without a recognition group.
