Abstract
Using Sonogashira coupling reaction,a novel asymmetric phenylacetylene halfcycle:1-{3-bromo-5-[2-(2-ethoxyethoxy)ethoxy]phenyl}ethynyl-3-{3-[(3,3-diethyl)triazene]-5-[2-(2-ethoxyethoxy)ethoxy]phenyl}ethynylbenzene was synthetized.The synthetic routes and reaction conditions were compared and discussed.The structures of the target compounds and intermediates were confirmed by1H NMR,13C NMR,EI-MS,HRMS techniques and element analysis.
