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.
