Question

Reaction mechanism of alcohol with thionyl chloride

Answer 1

Answer:

Mechanism of the Reaction of Alcohols with Thionyl Chloride

First, a nucleophilic oxygen atom of the alcohol displaces a chloride ion from thionyl chloride to form a protonated alkyl chlorosulfite intermediate. Subsequent deprotonation of this intermediate by a base yields the alkyl chlorosulfite, an inorganic ester.
