提出了一种乙炔聚合的新催化剂TiCl_4-蒽镁·(THF)_3。此催化剂的特点是无论在极性或非极性溶剂中均具有较高的活性。实验表明,不同的溶剂对产物聚乙炔的顺、反构型影响很大,芳烃溶剂有利于生成顺式构型。实验还发现乙炔能与蒽镁作用生成浅绿色的新化合物。
A novel acetylene catalyst TiCl_4-anthracene magnesium (THF) _3 was proposed. This catalyst is characterized by its high activity in both polar and non-polar solvents. Experiments show that different solvents have great influence on the cis and trans configuration of the product polyacetylene. Aromatic solvents are good for generating cis configuration. The experiment also found that acetylene can react with anthracene magnesium to generate a light green new compound.
