Highlights in Organic Chemistry [ Exploitation of Acetylenic Coupling Reactions in the Synthesis of Extended Tetrathiafulvalenes]

Acetylenic coupling reactions allow for construction of a wide variety of redox-active extended tetrathiafulvalenes (TTFs) from simple acetylenic dithiafulvene building blocks. This highlight covers the synthesis of such acetylenic TTF scaffolds with oligoyne, di-, tri-, or tetraethynylethene cores.
