A process for the preparation of 1,1'-oxy-bis(3-trifluoromethyl-4-nitrobenzene) which comprises reacting a compound of the formula ##STR1## where X is F, Cl, Br or I; with an inorganic base selected from the group consisting of alkali metal hydroxides, alkali metal carbonates, and alkali metal bicarbonates, in the presence of a catalytic quantity of a benzoate catalyst. In addition, benzoate esters of 4-nitro-3-trifluoromethylphenol may be isolated.
制备1,1'-氧化物-双(3-三氟甲基-4-硝基苯)的方法,包括将式为##STR1##的化合物与选自碱金属氢氧化物、碱金属碳酸盐和碱金属氢碳酸盐的无机碱在苯甲酸催化剂的催化下反应。此外,可以分离出4-硝基-3-三氟甲基苯甲酸酯。
