Cover Picture: Efficient Synthesis of 1,4‐Bis‐heteroatom‐substituted Tetraselanylbenzenes via 1,4‐Dilithiation of Hexaselanylbenzene and Investigation on Their Electronic Properties (Chem. Asian J. 9/2017)

Tuning σ‐type orbital interactions : Mono‐ and bis‐substituted polyselanylbenzenes were synthesized via mono‐ and dilithiation of hexakis(phenylselanyl)benzene, respectively. Introduction of various heteroatom functionalities into hexaselanylbenzene changed the electronic properties depending on the σ‐symmetric circular orbitals that were formed by interactions between neighboring heteroatoms. This study gives insight into the molecular design for σ‐delocalized systems and helps develop tuning electronic properties of benzene derivatives by σ‐type orbital interactions derived from heteroatom functionalities.
