Thionyl Chloride → [(2-Chloroethyl)selanyl]benzene

One gram of the resulting 2-hydroxyethyl phenyl selenide was dissolved in 15 ml of CH2Cl2. One ml of thionyl chloride was dissolved in 5 ml of CH2Cl2 and was added to the solution of the 2-hydroxyethyl phenyl selenide. The reaction mixture was refluxed for 1 h. The solvent was evaporated off and the remaining product transferred to a separatory funnel using CHCl3. Twenty ml of water was added to the separatory funnel and was made weakly basic with 5% aqueous NaHCO3. The CHCl3 layer was removed from the separatory funnel, dried with sodium sulfate and removed from the product by rotary evaporation and then in vacuo.
