2,5-二壬氧基-1,4-二乙炔基苯的合成
The preparation of 1,4-diethynyl-2,5-bis-nonyloxy-benzene
【摘要】 以对二溴苯衍生物和甲基丁炔醇为原料,通过Sonogashira钯催化偶联反应得到的产物,在碱性条件下脱丙酮获得1,4-二乙炔基苯和标题化合物。并通过凝胶渗透色谱和核磁共振氢谱对目标产物的结构进行了确认。
【Abstract】 1,4-Diethynylbenzene and 1,4-diethynyl-2,5-bis-nonyloxy-benzene were prepared from p-dibromobenzene derivatives and 2-methyl-but-3-yn-2-ol by two steps of Sonogashira coupling reaction and removal of acetone in an alkaline medium.The structures of target products were characterized by GPC and 1HNMR.
