and thermoplastic polymer materials. Specifically, triglycerides were converted into N-hydroxyalkyl fatty amides with the aid of amino alcohols via a mild base-catalyzed amidation process with nearly quantitative yields without the use of column chromatography and organic solvents. These fatty amides were further converted into a variety of methacrylate monomers, cyclic norbornene monomers and imino
来自可再生资源的可持续燃料,
化学物质和材料最近在全球范围内获得了巨大的发展势头,尽管要使它们与石油同行相比更具竞争性也有许多不小的障碍。我们展示了一种将植物油转化为可聚合单体和热塑性聚合物材料的稳健策略。具体而言,将
甘油三酸酯转化为氮-羟基烷基脂肪酰胺借助
氨基醇,通过温和的碱催化酰胺化过程,几乎可以定量收率,而无需使用柱色谱法和有机溶剂。这些脂肪酰胺进一步转化为各种
甲基丙烯酸酯单体,环状
降冰片烯单体和亚
氨基醚单体。来自选定单体的代表性聚合物表现出极大的不同物理性质,具有微妙的结构变化,突出了这种特定的酰胺化反应在
