Abstract

Highly active tungsten complexes supported by (Z)-1-(((2-hydroxyphenyl)imino)methyl)naphthalen-2-ol (L_A) and (Z)-4-chloro-2-(((2-hydroxyphenyl)imino)methyl)phenol (L_B) were synthesized and characterized. The ring-opening metathesis polymerization activities were assessed using ⁱBu₃Al as the co-initiator at room temperature. A 100% conversion of norbornene to high-molecular-weight polynorbornene (PNB) was obtained within 10 min with tunable cis/trans selectivity of resultant polymer depending on the ligand architecture.
