Polymerization of phenylacetylene by Lewis acid activated tungsten carbonyl complexes
TL;DR: Several tungsten carbonyl complexes exhibit catalytic activity towards polymerization of phenylacetylene (PA) in the presence of ZrCl4 as mentioned in this paper, which can give soluble, high molecular weight polymers in good yields.
