2,3-Dichloro-1-benzothiophene is an organochlorine compound that is a colorless solid. It has the formula CHClS and it is used as a precursor to other compounds. 2,3-Dichloro-1-benzothiophene can be prepared by reacting phenylphosphine with hydrogen chloride in the presence of chlorine:
2PCl + 2HCl → 2CHClS + PCl
It can also be synthesized from 1,4-dichlorobenzene and sulfuric acid. The chemical reactions for this are shown below:
2C6H4Cl2 + H2SO4 → (CH)5CO2H + Cl2
The product is purified by recrystallization or distillation. The major use of 2,3-dichloro-1-benzothiophene is as a precursor to other compounds such as
