Selective formation of 4-phosphanylated 1,2-dialkyl imidazole-2-thiones 3a–f has been obtained via a lithiation followed by phosphanylation reaction. The reactivity of 3a–f was examined towards oxidation and complexation reactions. All products were unambiguously characterized by elemental analyses, spectroscopic and spectrometric methods including X-ray analysis (3a, 3b, 4b, 4d, 5b, 6a and 6d).
通过锂化反应后进行磷化反应,成功选择性合成了4-磷化的1,2-二烷基咪唑-2-硫酮3a–f。对3a–f的反应性进行了氧化和络合反应的研究。所有产物通过元素分析、光谱学和质谱学方法(包括X射线分析)进行了明确表征(3a、3b、4b、4d、5b、6a和6d)。
