Halogen sulfur halides

Schwefel-gold, n. gold sulfide, -grube,/. sulfur pit, sulfur mine, -halogen, n. sulfur halide. 

Halogen abstraction from hypervalent sulfur halides has also been reported for the imidazol-2-ylidenes (IV) (Scheme 8.22). This reaction gives a nice example of the synthetic utihty of V-heterocyclic carbenes. Indeed, this adduct is the first structurally characterized derivative featuring the chlorosulfite ion (SO2CI ). ... 

The complexes of thiuram disulfide can be oxidized by an excess of halogens to products containing the bis(iminio)trithiolane dication (113).122 123 One of the sulfur atoms is removed as free sulfur or as sulfur halide. According to some reports the bis(iminio)tetrathiolane dication (114) also exists.124 In our investigations, however, we could not obtain any proof of this ion. The electrochemical literature about the oxidation of thiuram disulfide is also contradictory.125,126 Apart from the trithiolane ion a dithietane ion (115) is prepared by oxidation of dimethylformamide with bromine.127 As far as we know, no other disulfide can be oxidized to an analogous dication. 

Sodium fusion for detection of halogens, nitrogen, sulfur. When an organic compound is heated with metallic sodium, decomposition occurs. Free carbon is deposited, and some carbon monoxide and dioxide are formed. The halogens forms halides (NaCl, NaBr, and Nal). Nitrogen in presence of carbon and sodium gives sodium cyanide, NaCN sulfur forms sodium sulflde, NajS.
