In this paper we revisit earlier work relating to monoatomic atoms and ions published by pioneers in the area of electrostatic potentials. We include plots of the radial distributions of the electrostatic potentials for spherically symmetric atoms and cations, and for singly, doubly and triply negative anions. For atoms with anisotropy in their densities and electrostatic potentials, such as the halonium cations, it is shown how the molecular surface approach for plotting electrostatic potentials complements that achieved by directional radial distributions.

Article Synopsis
- A new family of ligands, called biaryl phosphacyclic ligands, is created from phobane and phosphatrioxa-adamantane structures.
- These ligands are effective in facilitating the Suzuki-Miyaura cross-coupling reactions of tough aryl bromides and chlorides.
- Notably, they can engage in reactions with challenging sterically hindered and heterocyclic compounds at room temperature.
