ResumoAbstract The carbene adducts 3 are obtained as stable solids from the imidazol-2-ylidenes 1 and CS 2 . 3 c reacts with bromine to give the cationic bromosulfane 4, whereas iodine forms the charge-transfer adduct 5. Oxidative coupling to the dicationic disulfane 6 is observed with excess of iodine. The X-ray structure analyses of 3b, 4, 5 and 6 are reported.
