我们曾报道了钼、钨卡宾络合物对炔烃的催化聚合作用和聚合机理。本文首次报道应用钨卡宾和AlCl_3(无水,下同)组成催化体系,催化炔烃聚合.发现此催化体系对乙炔、单取代乙炔(如苯乙炔、氯丙炔)和双取代乙炔(如二苯乙炔、1,4-二氯-2-丁炔)的聚合均具有一定的催化活性,尤其是对二苯乙炔的催化聚合的效果更好。 We have reported the catalytic polymerization of alkyne and the polymerization mechanism of molybdenum and tungsten carbene complexes. This paper reports for the first time the catalytic system of catalysis of alkyne using tungsten carbides and AlCl3 (anhydrous, the same below) to catalyze the polymerization of acetylene. The catalytic system was found to have good catalytic activity for acetylene, monosubstituted acetylenes (such as phenylacetylene and chloropropyne) and disubstituted acetylenes Phenylacetylene, 1,4-dichloro-2-butyne) have a certain catalytic activity, especially for the catalytic effect of the stilbene better.
