Unsymmetrical and Highly-Conjugated Tetrathiafulvalene and Selenatrithiafulvalene Derivatives: Synthesis and Reactions of Novel Heterocyclic Wittig-Horner Reagents.

Novel 1,3-dithiole and 1-selena-3-thiole Wittig–Homer reagents have been developed and used in the efficient synthesis of a range of new, unsymmetrical tetrathiafulvalene and selenatrithiafulvalene derivatives (6)–(10) and (16); cyclic voltammetry establishes that these molecules are efficient π-donors.
