【Abstract】 Catalyzed by palladium complex, the oligomerization processes of acetylenes occured to give the corresponding polysubstituted benzene derivatives or coupling compounds.Influences of the catalysts and ligands,structure of acetylene,solvents,oxidants,reaction time as well as temperature were studied,and possible mechanisms were also discussed.更多还原
