What is Thionyl chloride?
The Uses of Thionyl chloride
Thionyl chloride (SOCl2) is used as a chlorinating agent in manufacturing organic compounds. It is also used as a solvent in high-energy lithium batteries.
The Uses of Thionyl chloride
A mixture of the SM (1.0 g, 6.3 mmol) in ACN (20 mL) was treated with SOCl2 (0.8 mL). The resulting mixture was refluxed for 2 h. The solvent was removed in vacuo to provide the crude product as an oil which was used in the next step without further purification.
