Acetic acid, trichloro-, ethyl ester: Does not have an individual approval but may be used under an appropriate group standard
使用Ethyl trichloroacetate was used in the synthesis of dichlorocarbon precursor, phenyl(trichloromethyl)methyl.
一般的な説明Ethyl trichloroacetate undergoes atom-transfer radical addition reaction with styrene catalyzed by the Ru-pentamethylcyclopentadienyl complexes.
製造方法Ethyl trichloroacetate is synthesized from trichloroacetic acid and ethyl alcohol by the esterification reaction. synthesis steps: Trichloroacetic acid(TCA), anhydrous ethyl alcohol and sulfuric acid are heated together and refluxed for 6 h. After cooling, the ester layer is separated by pouring into water, neutralized with 5-10% sodium carbonate solution, washed with water and dried overnight with anhydrous calcium chloride. After filtration, distillation was carried out to obtain the finished product. Yield 75%.
純化方法Shake the ester with saturated aqueous Na2CO3 (three times), aqueous 50% CaCl2 (three times), saturated aqueous NaCl (twice), then distil over CaCl2 and redistil it under reduced pressure. [Beilstein 2 IV 514.]
