反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Similarly by using diethyl bromomethylmalonate in place of diethyl bromomalonate, and carrying out the reaction with 5-(2-chloro-4-trifluoromethylphenoxy)-2-nitrophenol, 5-(2,6-dichloro-4-trifluoromethylphenoxy)-2-nitrophenol or 5-(2-chloro-6-fluoro-4-trifluoromethylphenoxy)-2-nitrophenol, diethyl 2-[5-(2-chloro-4-trifluoromethylphenoxy)-2-nitrophenoxy]-2-methylmalonate (IV-2), diethyl 2-[5-(2,6-dichloro-4-trifluoromethylphenoxy)- 2-nitrophenxoy]-2-methylmalonate (IV-3) and diethyl 2-[5-(2-chloro-6-fluoro-4-trifluoro methylphenoxy)-2-nitrophenoxy]-2-methylmalonate (IV-4) were obtained. The physical properties of these compounds are shown in Table 2.
