Unsymmetrical and highly-conjugated tetrathiafulvalene and selenatrithiafulvalene derivatives: synthesis and reactions of novel heterocyclic Wittig–Horner reagents

Abstract

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.
