The synthesis of 3,4-diphenyl-3,4-dichlorocyclobutanodicarbox-1,2-dianilides (new chloro-derivatives of truxinic acid) is reported. Structure elucidation based on IR, MS, 1H NMR, 13C NMR, Raman, and X-ray analysis clear up structural ambiguities as well as revealing the compound to be β-stereoisomer. A radical combination of two molecules of benzoylacetanilide in the presence of POCl3 is postulated
据报道,合成了3,4-二苯基-3,4-二氯环丁二boxbox-1,2-二苯甲腈(新的精氨酸酸的氯代衍生物)。基于IR,MS,1 H NMR,13 C NMR,拉曼光谱和X射线分析的结构阐明消除了结构歧义,并揭示了该化合物为β-立体异构体。假定在POCl 3存在下,两个分子的苯甲酰基乙酰苯胺的自由基结合。
