reportActive / Technical Report | Accession Number: ADA264133 | Open PDF

Abstract:

Well-defined molybdenum ROMP catalysts that contain C2-symmetric diolate ligands tartrates, binaphtholates, or biphenolates have been prepared and shown to polymerize 2,3-R2norbornadienes R CF3 or CO2Me to give, in the most favorable case, 99 cis polymers that are 99 tactic.... ROMP Ring Opening Metathesis Polymerization, Tartrates, Binaphtholates, Biphenolates, Cis polymers, Norbornadienes.
