【摘要】 以对-溴甲苯、对苯二酚、1-溴己烷、1,4-对苯二异氰酸酯等为原料,通过Williamson反应、溴化反应、格氏反应、氧化反应、Suzuki反应等一系列反应合成了用于合成梯形聚合物的两种重要单体:2,5-二[4′-N-(1,1-二羟甲基)丙胺基甲酰苯基]-1,4二己氧基苯和2,5-二{4′-N-[1,1-二(对异氰酸酯基苯胺甲酸酯基)丙胺基甲酰苯基]}-1,4二己氧基苯,并利用元素分析、红外光谱(IR)、核磁共振氢谱(1HNMR)和质谱(MS)等手段对其进行了结构表征.更多还原

【Abstract】 As important monomers for preparation of ladder-like polymers,two new types of structurally ordered ladder-like compounds,2,5-bis[4’-N-(1,1-dihydroxylmethyl)-propylamidocyanogen-methylacylphenyl]-1,4-bishexyloxybenzen(M1)and 2,5-bis-{4’-N-[1,1-bis(4-isocyanatephenylamidocyanogenformylester)propylamidocyanogen-methylacylphenyl]}-1,4-bishexyloxybenzene(M2),were synthesized by a series of reactions such as Williamson reaction,bromination reaction,Grignard reaction,oxidation reaction,and Suzuki coupling reaction with p-bromotoluene,1,4-hydroquinone,1-bromohexane,toluene diisocyanate etc.as starting materials.The compositions and structures of M1 and M2 were characterized via elemental analysis,infrared resonance(IR)spectroscopy,proton nuclear resonance(1H NMR)and mass(MS)spectroscopy.更多还原
