Liquid-phase fluorination and dehydrochlorination of 1,1,1-trichloroethane

During the liquid-phase fluorination of 1,1,1-trichloroethane with SbCl5*HF, 1,1-dichloroethene is formed.This reacts to give linear and branched oligomers.The hydrolysis of these by-products affords 3,5-dichlorophenol, 6-methyl-4-chloro-2-pyran-2-one and 2-methyl-5,7-dichlorochromone whose source is the acid-catalyzed reaction of water with the trimer and pentamer of 1,1-dichloroethene.
