Three new coupling agents with different numbers of N-acyl lactam and 4H-3,1-benzoxazin-4-one groups were synthesized. A selective stepwise conversion of the coupling agents with 1-dodecanol and 1-dodecylamine was demonstrated by means of solvent-free model reactions in melt at 195 and 210 °C, respectively. These coupling agents are regarded as potential cores for the synthesis of novel star-like compounds
合成了三种具有不同数量的N-酰基内酰胺和4个H -3,1-苯并恶嗪-4-酮的新型偶联剂。借助无溶剂模型反应分别在195和210°C的熔体中证明了偶联剂与1-十二烷醇和1-十二烷基胺的选择性逐步转化。这些偶联剂被认为是合成新型星形化合物和聚合物的潜在核心,这些星形化合物和聚合物的臂的类型和长度各不相同。
