中文摘要：
2-Phenyl-3-thioformylindolizine 和 1,2-dimethyl-3-thioformylindolizine 经历面对 tributylphosphine 联合反应在高收益给(E)-1,2-bis(3-indolizinyl)ethenes 的新奇 desulfur。产品的结构被红外， 1H NMR， MS，元素的分析和单个水晶 X 光检查衍射分析证实。涉及反应的各种各样的阶段的机制被讨论。
英文摘要：
2-Phenyl-3-thioformylindolizine and 1,2-dimethyl-3-thioformylindolizine undergo a novel desulfur coupling reaction in the presence of tributylphosphine to give （E）-1,2-bis（3-indolizinyl）ethenes in high yields. The structures of products were confirmed by IR, ^1H NMR, MS, elemental analysis and single crystal X-ray diffraction analysis. The mechanisms involved in various stages of the reaction were discussed.
