该反应通过[4 + 2]环加成得到四氯眼二甲酯和[6 + 2]环加成得到2-氯-3-乙氧羰基-2-三氯-2-硫代琥珀酸二甲酯。后一种结构经x射线晶体学证实,纠正了早先的报告。
The title reaction yields two products, dimethyl tetrachlorophthalate, by [4 + 2] cycloaddition and dimethyl 2-chloro-3-ethoxycarbonylimino-2-trichloro-2-thienylsuccinate by [6 + 2] cycloaddition. The latter structure, verified by X-ray crystallography, corrects an earlier report.
