## Abstract 4,9‐Diethyl[1,4]dihydrodithiino[5,6‐__f__]benzotrithiole (DTBT) gave a radical cation, DTBT(•+), and a dication, DTBT(2+), on treatment with a single‐electron oxidizing reagent. Both compounds showed an ESR signal, whereas the dication, generated by this procedure, was silent for ^1^H N
