Abstract It was demonstrated that N-(1-methoxyalkyl)amides do not react with trimethyl phosphite under neutral or basic conditions. The treatment of N-(1-methoxyalkyl)amides with trialkyl phosphites or dialkyl phosphonites, triphenylphosphonium tetrafluoroborate, and Hünig's base caused immediate formation of the corresponding 1-(N-acylamino)-alkyltriphenylphosphonium tetrafluoroborates, followed by
摘要 研究表明,N-(1-甲氧基烷基)酰胺在中性或碱性条件下不与亚磷酸三甲酯反应。用亚磷酸三烷基酯或亚磷酸二烷基酯、四氟硼酸三苯基鏻和 Hünig's 碱处理 N-(1-甲氧基烷基)酰胺导致相应的 1-(N-酰基氨基)-烷基三苯基鏻四氟硼酸盐立即形成,随后是缓慢的 Michaelis-Arbuzov 样鏻盐与亚磷酸酯或亚膦酸酯反应生成 α-(N-酰基氨基)-烷烃膦酸酯或 α-(N-酰基氨基)烷烃次膦酸酯。假设 N-(1-烷氧基烷基)酰胺、三苯基四氟硼酸盐、1-(N-酰基氨基)烷基三苯基-盐、N-酰基亚胺和N-酰基胺盐之间达到平衡,讨论了所考虑的转化的合理机制。
