Thionyl Chloride → HCID 14461279, compound

Participants

Reaction Steps

39.4 parts by weight of thionyl chloride are added to a suspension of 65 parts by weight of m-(1,1,2,2-tetrafluoroethoxy)-benzoic acid in 500 parts by volume of 1,2-dichloroethane and the mixture is stirred for 3 hours under reflux. It is then concentrated under reduced pressure, and after filtering off a small amount of starting material which has precipitated, m-(1,1,2,2-tetrafluoroethoxy)-benzoyl chloride is obtained as a yellowish oil. The IR spectrum shows C=O bands at 1,770 and 1,748 cm-1 and fluoroalkoxy bands at 1,225, 1,190 and 1,125 cm-1.
