三苯甲烷-4,4',4'-三羧酸的合成

摘要

报道了三苯甲烷-4,4',4"-三羧酸(TTCA)的合成方法.以三(乙酰基苯基)甲(TAcPM)为原料,经溴仿反应,得到全对位羧基取代的三苯甲烷;考察了反应物配比、溶剂和反应时间等因素对产率的影响,并利用核磁共振谱、傅立叶变换红外光谱和元素分析等表征了产物的结构和组成.%A novel method for synthesizing triphenylmethane-4.4′, 4"-tricarboxylic acid (TTCA) is reported. Title compound was synthesized via the bromoform reaction of tris(p-acetyphenyl) methane as the starting material. The effects of reactant molar ratio, solvent and reaction time on the yield of target product were investigated. The structure and composition of the target product were analyzed by means of nuclear magnetic resonance (1H NMR) spectroscopy, Fourier transformation infrared spectrometry, and elemental analysis.
