Yasir, Mohammad; Kilbinger, Andreas F. M. published their research in ACS Macro Letters in 2021. The article was titled 《Cascade Ring-Opening/Ring-Closing Metathesis Polymerization of a Monomer Containing a Norbornene and a Cyclohexene Ring》.Recommanded Product: 172222-30-9 The article contains the following contents:
Norbornene is polymerized extremely fast when reacted with Grubbs’ first (G1) or third generation catalyst (G3) because of its very high ring strain energy. Cyclohexene, on the other hand, cannot be polymerized using G1 or G3 due to its very low ring strain energy. Subsequently, the sequence-selective polymerization of these two monomers is extremely challenging. A sequence-selective cascade ring-opening/ring-closing metathesis polymerization of the monomer M containing both the norbornene and the cyclohexene ring using G1 or G3 is reported. The polymer structure was analyzed by 1H NMR, 1H-1H COSY, and 1H-1H ROESY spectroscopy and MALDI-ToF mass spectrometry. Polymers with moderate mol. weight dispersities and good mol. weight control were achieved by varying the ratio between monomer M and G1.Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9Recommanded Product: 172222-30-9) was used in this study.
Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9) is a ruthenium-based olefin metathesis catalyst. It is useful for olefin cross metathesis (CM) and ring closing metathesis (RCM) of terminal olefins under a variety of reactions conditions, and so on.Recommanded Product: 172222-30-9
