Abstract:The synthesis of three new unsymmetrical tetrathiafulvalenes (TTFs), all fused with dihydrooxathiino rings, is described.The new donors all showed two reversible cyclic voltammetric halfwaves at values lower or similar to the value of bis(ethylenedithi0)-TTF. The dimethyl derivative DMOX-TTF, 5, gave well formed radical cation salts of close to 2 : 1 stoichiometry with several anions.
“…Low yields were obtained in many cases, ,− and a study of the mechanism of the reaction was carried out using the synthesis of DMBTTF (dimethylbenzotetrathiafulvalene) as a model (Scheme ). , 31 …”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
