Sonogashira coupling of buta-1,3-diynylbenzene with ((2-iodophenyl)ethynyl)trimethylsilane and 1,2-diiodobenzene led to the novel enetriyne, 1-ethynyl-2-(phenylbuta-1,3-diynyl)benzene, and enetetrayne, 1,2-bis(phenylbuta-1,3-diynyl)benzene, respectively. Solid state structural and thermal analyses are also described. In solution, 1-ethynyl-2-(phenylbuta-1,3-diynyl)benzene was found to undergo thermal
buta-1,3-diynylbenzene与((2-iodophenyl)ethynyl)trimethylsilane和1,2-diiodobenzene的Sonogashira偶联导致了新的三烯,1-ethynyl-2-(phenylbuta-1,3-diynyl)苯和乙炔,1,2-双(苯基丁-1,3-二炔基)苯。还描述了固态结构和热分析。在溶液中,发现1-乙炔基-2-(苯基丁-1,3-二炔基)苯经历热伯格曼环化反应,得到2-(苯基乙炔基)萘。
