The development of synthetic methodologies for the synthesis of functionalised tetrathiafulvalenes' has largely been stimu- lated by the search for new tetrathiafulvalene-based organic metals.2 Furthermore, there has recently been a steadily increasing interest in incorporating the tetrathiafulvalene into macrocyclic and supramolecular compounds,3 but the lack of an easily functionalisable tetrathiafulvalene derivative has severely restricted the speed of progress ...
