实验步骤: A stirred mixture of 38.8 g (0.2 moles) trichloroacryloyl chloride, 18.5 g. (0.2 moles) aminoacetonitrile hydrochloride and.150 ml chloroform was refluxed for thirty hours, with evolution of gas and dissolution of most of the aminoacetonitrile hydrochloride. The mixture was filtered hot to remove unreacted aminoacetonitrile hydrochloride. The filtrate was stripped to give an oil. The oil was rubbed with hexane and soon solidified to give 36.1 g of the above-identified product as an off-white solid, which liquified at about 56°-59° C. A small portion of product was recrystallized from a benzene-hexane mixture to give a white solid, melting point 58°-60° C. The mixture was filtered hot to remove unreacted aminoacetonitrile hydrochloride to give an oil

实验步骤: A slurry of 38.8 g (0.2 mol) trichloroacrylyl chloride and 18.5 g (0.2 mol) aminoacetonitrile hydrochloride in 150 ml chloroform was stirred and heated under reflux for 30 hours, while gases evolved and most of the hydrochloride salt dissolved. The reaction mixture was filtered while hot and the solvent evaporated under reduced pressure to give 36.1 g of N-cyanomethyl trichloroacrylamide, as an off-white solid melting at 56°-59° C. Recrystallization from benzene-hexane gave a white solid melting at 58°-60° C. Elemental analysis for C5H3Cl3N2O showed: %Cl, calc. 49.8, found 50.0. heated under reflux for 30 hours, while gases dissolved The reaction mixture was filtered while hot and the solvent evaporated under reduced pressure

实验步骤: 2.85 g of 1,3-dimethyl-4-(2,4-dichlorobenzoyl)-5-hydroxy pyrazole and 1.01 g of triethylamine were dissolved in 20 ml of benzene. 1.94 g of trichloroacrylic acid chloride were dropped into the solution. The reaction mixture was stirred for 3 hours at the reflux temperature of benzene. After the completion of the reaction, water was added to the reaction mixture, the organic layer was separated and dried. Benzene was distilled off under reduced pressure to give 3.3 g of 1,3-dimethyl-4-(2,4-dichlorobenzoyl)-5-trichloroacryloyloxy pyrazole as colorless crystals of melting point 141° to 142° C. was added to the reaction mixture the organic layer was separated dried Benzene was distilled off under reduced pressure
