The cyclic anhydrides are broadly employed in several fields, such as the chemical, plastic, agrochemical, and pharmaceutical industries. This study describes the chemical reactivity of 4,5-dichlorophthalic anhydride towards several nucleophiles, including thiosemicarbazide and different amines, to produce the carboxylic acid derivatives resulting from anhydride's opening, namely, phthalimide and dicarboxylic acid (-) products. Their chemical structures are confirmed by NMR, IR and MS spectra analyses. Density-functional theory (DFT) studies are performed using (DFT/B3LYP) with the 6-311G(d, p) basis sets to recognize different chemical and physical features of the target compounds.
环状酸酐在化学、塑料、农用化学品和制药等多个领域得到广泛应用。本研究描述了 4,5-二氯邻苯二甲酸酐对多种亲核试剂（包括缩硫代氨基脲和不同的胺）的化学反应性，以生成酸酐开环得到的羧酸衍生物，即邻苯二甲酰亚胺和二羧酸（-)产物。它们的化学结构通过 NMR、IR 和 MS 谱分析得到确认。使用密度泛函理论（DFT）研究（DFT/B3LYP）与 6-311G(d, p)基组相结合，以识别目标化合物的不同化学和物理特性。
