Abstract:
Selenium based diaryl dichalcogenides are compounds that are receiving attention in organic synthesis as eco-friendly oxidation agents as well as in pharmaceutical chemistry, where, together with tellurium-based derivatives, are appealing drugs mainly for their antioxidant properties. A benchmark study to establish optimal density functional theory (DFT) methods for the description of their molecular and electronic structure as well as for their energetics is presented here. Structural features, such as the orientation of the phenyl rings, as well as energetic aspects, i.e., the chalcogen-chalcogen bond strength, are discussed, with the aim of applying the novel insights to quantum mechanics-based investigations of their reactivity and to facilitate drug design. © 2016 Wiley Periodicals, Inc.

Conformation
The simplest example of a diene is 1,3-butadiene, an acyclic conjugated π system. At room temperature, the molecule exists as a mixture of s-cis and s-trans conformers by virtue of rotation around the carbon–carbon single bond. Although the s-trans isomer is more stable,...
