A series of thiadiazole-based dithiafulvalene (DTF) derivatives has been synthesized in moderate yields via iodine-mediated oxidative vinylic C(sp2)–H sulfenylation with mercapto-thiadiazoles. The formation of C(sp2)–S bond was confirmed and characterized by NMR and single crystal X-ray diffraction studies. This new protocol is simple and effective for preparation DTF containing thiadiazole group.
