Ring-opening metathesis polymerization of Norbornene-derived cyclic olefins using Iminomethyl-hydroxyl-ligated tungsten Complexes: Fast reaction and tunable cis/trans selectivity
Highly active tungsten complexes supported by (Z)-1-(((2-hydroxyphenyl)imino)methyl)naphthalen-2-ol (LA) and (Z)-4-chloro-2-(((2-hydroxyphenyl)imino)methyl)phenol (LB) 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.
期刊介绍：
Launched in January 1998, Inorganic Chemistry Communications is an international journal dedicated to the rapid publication of short communications in the major areas of inorganic, organometallic and supramolecular chemistry. Topics include synthetic and reaction chemistry, kinetics and mechanisms of reactions, bioinorganic chemistry, photochemistry and the use of metal and organometallic compounds in stoichiometric and catalytic synthesis or organic compounds.
