已开发出合成六元杂环的新方法 - 2-R-2-oxo-4-aryl-2H-benzo[e][1,2]-oxaphosphorin-3-enes。它包括亚芳基二氧基三卤代正膦与芳基乙炔的相互作用。在这个不寻常的反应中发生了磷酰基和 PC 键的形成、芳香氧的同位取代和苯环的卤化。讨论了正膦结构对合成结果的影响。如果正膦苯环的两个对位都被卤素占据,就会产生卤素分子。2-R-2-oxo-4-aryl-2H-benzo[e][1,2]-oxaphosphorin-3-enes 的结构是通过 X 射线分析确定的。
The structure of products of reaction ofo-phenylenedioxytrichlorophosphorane with arylacetylenes
摘要:
The products of reaction of o-phenylenedioxytrichlorophosphorane with arylacetylenes were identified as 4-aryl-2-chloro-2-oxo-5,6-(4-chlorobenzo)phosphorin-3-enes using H-1, C-13, P-31 NMR, and IR spectroscopy and high-resolution mass spectrometry.
