3-P-(P-(P-甲氧基苯乙炔基)苯乙炔基)苯氧基丙烯酸丙酯合成与表征

摘要

Synthesis and characterization of 3-[ p-( p-( p- methoxyphenylethynyl) phenylethynyl) Phenoxy ] propylacrylate was synthesized from 4-Ethynylanisole, p-Bromophenol ,3-chloro-I-propanol and 2-methyl-3-Butyn-2-ol via williamson reaction, esterification reaction, followed by Sonogeshina c-c coupling reaction. The as-synthesized compound was characterized by using elemental analysis ,IR and :H NMR. The Reactant dosage,catalyst and the like were discussed as the factors that influenced the yield of the reaction products.%以对甲氧基苯乙炔、对溴苯酚、3-氯-1-丙醇和甲基丁炔醇等为原料,通过williamson反应、Sonogashina和酯化等反应合成3[P-(P-(P-甲氧基苯乙炔基)苯乙炔基)苯氧基]丙烯酸丙酯.用元素分析,IR和1HNMR等手段对产物的组成和结构进行了表征,并讨论反应物量、催化剂等因素对产率的影响.
