ABSTRACT An efficient and reproducible microwave-assisted synthesis of dialkyl ω-azidoalkylphosphonates via nucleophilic substitution of the appropriate dialkyl ω-bromoalkylphosphonates by sodium azide in water or dimethylformamide (DMF) as solvent has been developed. This process has been optimized for batch reactors. The target, structurally diverse dialkyl ω-azidoalkylphosphonates with different
摘要 已开发出一种高效且可重复的微波辅助合成 ω-叠氮烷基膦酸二烷基酯,方法是通过在水或二甲基甲酰胺 (DMF) 溶剂中的叠氮化钠对合适的二烷基 ω-溴烷基膦酸酯进行亲核取代。该工艺已针对间歇式反应器进行了优化。目标,结构多样的二烷基 ω-叠氮烷基膦酸酯在膦酸酯基团周围具有不同的空间位阻,并含有不同长度(n = 2-6)的未支化侧碳链,已以中等至高产率(39-87%)获得。图形概要
