  摘要：

  From 3,4,4-trichloro-3-butenoic acid 3,3,4,4,4-pentachlorobutanoic, 3,4,4,4-tetrachloro-2-butenoic, and 2,3,4,4-tetrachloro-3-butenoic acids were synthesized. By Friedel-Krafts reaction from 3,4,4-trichloro-3-butenoyl and 3,3,4,4,4-pentachlorobutanoyl chlorides with aromatic hydrocarbons the corresponding aryl chloroalkyl ketones were prepared. It was established that dehydrochlorination of 2,2,3,3,3-pentachloropropyl phenyl ketone with aqueous alkali under conditions of the phase-transfer catalysis at the molar ratio of reagents ketone: KOH: triethylbenzylammoniurn chloride equal to 1: 4: 0.05 involved the cleavage of two HCl molecules and resulted in 3,3,3-trichloro-1-propynyl phenyl ketone.
