1a–c with phosphorus decasulfide P4S10 in dry pyridine afforded some novel pyridine solvate of 1,3,4,2‐thiadiazaphospholes 2a–c. Similarly, treatment of their corresponding hydrazones 3a–c toward phosphorus decasulfide under the same reaction conditions gave the corresponding thio‐analog 4 and 1,3,2‐benzoxazaphosphinine and benzodiazaphosphinine pyridine solvates 5a,b, respectively. Treatment of (thio)semicarbazides
在干燥的吡啶中,将某些选定的苯甲酸酰肼1a – c与十硫化二磷P 4 S 10反应,得到一些新颖的1,3,4,2-噻二氮杂磷2a – c吡啶溶剂化物。同样,在相同的反应条件下,将相应的3a - c对十硫化二磷进行处理,得到相应的硫代类似物4和1,3,2-苯并恶唑膦和苯二氮膦膦吡啶溶剂化物5a,b, 分别。在干燥的吡啶中用十硫化二磷处理(thio)semicarbazides及其相应的(thio)semicarbazones,分别产生了新的1,2,4,3-三氮杂磷腈6a,b和1,3,2-二氮杂磷啶8a,b。此外,用十硫化二磷环化(硫代)碳酰肼及其单(硫代)碳酰肼类化合物分别产生1,2,4,3-三氮杂磷腈9a,b和11a,b。这些产物的结构由分析和光谱数据证实。
