  Synthesis of 3,4-dibromo-3,4,4-trichloro-1-phenylbutan-1-one and 1-aryl-2-bromo-3,4,4-trichlorobut-3-en-1-ones from 3,4,4-trichlorobut-3-enoic acid

  摘要：

  Bromination of 3,4,4-trichlorobut-3-enoic acid in boiling carbon tetrachloride led to the formation of 2-bromo-3,4,4-trichlorobut-3-enoic acid as a result of replacement of hydrogen in the CH2 group. The reaction at 40 degrees C involved the double C=C bond to give 3,4-dibromo-3,4,4-trichlorobutanoic acid. The brominated acids were converted into the corresponding chlorides which were used to acylate benzene, toluene, and bromobenzene according to Friedel-Crafts. The acylation was not selective, and only the reaction of 3,4-dibromo-3,4,4-trichlorobutanoyl chloride with benzene gave 3,4-dibromo-3,4,4-trichloro-1-phenylbutan-1-one as the only product. 1-Aryl-2-bromo-3,4,4-trichlorobut-3-en-1-ones were synthesized by bromination of the corresponding 1-aryl-3,4,4-trichlorobut-3-en-1-ones which were prepared previously by Friedel-Crafts acylation of substituted benzenes with 3,4,4-trichlorobut-3-enoyl chloride.

  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.

  An efficient procedure have been developed for the selective reduction of the carbonyl group in phenyl trichlorovinyl ketone and aryl trichloroallyl ketones by the action of NaBH4 in propan-2-ol to obtain the corresponding alcohols. The hydroxy group in the latter was converted into amino by the Ritter reaction. Treatment of the alcohols and amines with 5-phenylisoxazole-3-carbonyl chloride and 4,5-dichloroisothiazole-3-carbonyl chloride gave the corresponding esters and amides, and condensation of the amines with aromatic aldehydes afforded Schiff bases.

  The reaction of 1-aryl-3,4,4-trichlorobut-3-en-1-ones with semicarbazide hydrochloride in the presence of sodium acetate is accompanied by prototropic allylic rearrangement, leading to the formation of two isomeric products, semicarbazones of the initial ketones and 1-aryl-3,4,4-trichlorobut-2-en-1-one semicarbazones. The latter undergo heterocyclization in the presence of triethylamine to give the corresponding 3-aryl-5-dichloromethyl-1H-pyrazole-1-carboxamides.
