the study of reactions of N-alkyl- and N-aryltrihalogenoacetamides with PCl5, it was demonstrated for the first time that 3-alkyl(aryl)-2,2,2,4 tetrachloro-4-trihalomethyl-1,3,2-λ5-oxazaphosphetanes are intermediates in the synthesis of trihaloacetimidoyl chlorides. According to quantum-chemical calculations, acyclic N-tetrachlorophosphoranes, which are the primary products in the reactions of trihaloacetamides
在 N-烷基-和 N-芳基三卤代乙酰胺与 PCl5 反应的研究中,首次证明了 3-烷基(芳基)-2,2,2,4 四氯-4-三卤甲基-1,3,2 -λ5-oxazaphosphetanes 是合成三卤代乙酰亚氨基酰氯的中间体。根据量子化学计算,三卤乙酰胺与 PCl5 反应的主要产物无环 N-四氯正膦快速环化为相应的磷酸酯,随后 1,3- 氯代迁移产生具有五配位 P 的氧氮杂膦原子。
