Sulfur dichloride at room temperature.

Diiminosuccinonitrile reacts with sulfur dichloride in dichloromethane at room temperature to give 1 2 5 thiadiazole 3 4 dicarbonitrile 226 in 93 yield 1972joc4136 the addition of catalytic naked chloride to the reaction mixture gave the bi 1 2 5 thiadiazole 227 1991cb1517 no experimental data were given for this transformation but it was shown that the bi 1 2 5 thiadiazole 227 can. Disulfur dichloride s 2 cl 2 is the most common impurity in scl 2. The reaction proceeds at usable rates at room temperature. S 8 4 cl 2 4 s 2 cl 2 δh 58 2 kj mol.

Disulfur dichloride s 2 cl 2 is the most common impurity in scl 2. In the laboratory chlorine gas is led into a flask containing elemental sulfur. With water the dichloride structures sulfuric corrosive sulfur and a blend of thionic acids h 2 s x o y. Technical grade sulfur dichloride is produced by passing gaseous chlorine into s2cl2 at low temperature until the correct chlorine content is reached.

Separation of scl 2 from s 2 cl 2 is possible via distillation with pcl 3 to form an azeotrope of 99 purity however sulfur dichloride loses chlorine slowly at room temperature. As disulfur dichloride is formed the contents become a golden yellow liquid. It is used in organic synthesis and adds chloride substituted thioethers to alkenes. Sulfur dichloride can be purified by distillation in the presence of stabilizers.

Separation of scl 2 from s 2 cl 2 is possible via distillation with pcl 3 to form an azeotrope of 99 purity however sulfur dichloride loses chlorine slowly at room temperature and reverts to disulfur dichloride.
