4,4′-双(2,4,6-三甲基苯甲酰基)二苯醚合成及结构分析

The Synthesis of 4, 4′-Bis(2, 4, 6-Trimethyl Benzoyl) Diphenyl Ether and Its Structure Analysis

在非质子极性溶剂中,强吸电子基团取代的硝基苯与碱金属亚硝酸盐作用,自身缩合生成取代二苯醚,是一新的合成方法。利用此法,合成出了一种新的化合物,此化合物在国内外尚未见到合成报导。经IR,~1H-NMR,MS及元素分析证明其结构确为4,4’-双(2,4.6-三甲基苯甲酰基)二苯醚。

In the presence of alkali nitrite, nitrobnzenes substituted by strongly electron withdrawing group undergo a self condensation in an aprotic polar solvent to give substituted diphenyl ethers. This is a new synthetic method. By the method, a new compound was prepared; It is verified that nowhere has it been synthesized at home and abroad. By means of IR, 'H-NMR, MS and element analysis, its structure was proved, to be 4, 4'-bis(2, 4, 6-trimethyl benzoyl) diphenyl ether.
