Sinclair (92) has described an improved method for the preparation of methyl 6-chloro-6-deoxy- -D-glucopyranoside (137) from methyl a-D-glucopyranoside (11). The reaction was effected with sulfur monochloride S2C12 in N,N-dimethylformamide at room temperature and the... 

Reaction of l-methyl-4-aminoimidazole (71 R1 = Me, R2 =H) with sulfur monochloride (S2C12) gave a product that was isolated and assumed to be the imidazo[4,5-c/]-l, 2,3-dithiazole (91) (56%) by analogy with other hetero-Herz reactions (84JOC1224). 

JPL Chlorinolysis [Jet Propulsion Laboratory] A process for desulfurizing coal by oxidation with chlorine. The sulfur becomes converted to sulfur monochloride, S2C12. Developed by the Jet Propulsion Laboratory of the California Institute of Technology from 1976 to 1981. 

Sinclair95 has described the preparation of methyl 6-chloro-6-deoxy-a-D-glucopyranoside from methyl a-D-glucopyranoside by treatment with sulfur monochloride (S2C12) in N,N-dimethylformam ide a yield of 30-35% was obtained on separation of the reaction products on a column of Darco G-60-Celite 535. 

Physical Properties. Sulfur monochloride [10025-67-9], S2C12, is a yellow-orange liquid with a characteristic pungent odor. It was first...

Sulfurized olefins (S2C12 plus isobutene) are further reacted with S and Na2S to give products useful as extreme pressure lubricant additives (144,145). The reaction of unsaturated natural oils with sulfur monochloride gives resinous products known as Factice, which are useful as art-gum erasers and rubber additives (146,147). The addition reaction of sulfur monochloride with unsaturated polymers, eg, natural mbber, produces cross-links and thus serves as a means for vulcanizing mbber at moderate temperatures. The photochemical cross-linking of polyethylene has also been reported (148). 

Manufacture, Sulfur monochloride is made commercially by direct chlorination of sulfur, usually in a heel of sulfur chloride from a previous batch. The chlorination appears to proceed stepwise through higher sulfur chlorides (S Cl, where x > 2). If conducted too quickly, the chlorination may yield products containing SC12 and S CL as well as S2C12. A catalyst, eg, iron, iodine, or a trace of ferric chloride, facilitates the reaction. The manufacture in the absence of Fe and Fe salts at 32—100°C has also been reported (149—151).

Carbon tetrachloride is now made by a method invented more than a century ago. Carbon disulfide (CS2) is treated with chlorine gas, producing sulfur monochloride (S2C13) and carbon tetrachloride CS2 + 12 -9 CC14 + S2C12.
