Selenium oxydichloride is the inorganic compound with the formula SeOCl2. It is a liquid with a high dielectric constant (55) and high specific conductance, and for these reasons is an attractive solvent. Structurally, it is a close chemical relative of thionyl chloride SOCl2 and DMSO as a donor solvent.
==Preparation and reactions==
Selenium oxydichloride can be prepared by several methods, and a popular one involves the conversion of selenium dioxide to dichloroselenious acid followed by dehydration:
:SeO2 + 2 HCl → Se(OH)2Cl2
:Se(OH)2Cl2 → SeOCl2 + H2O
The original synthesis involved the redistribution reaction of selenium dioxide and selenium tetrachloride.
The compound hydrolyzes readily.
