Ring-expansion metathesis polymerization (REMP) has shown potential as an efficient strategy to access cyclic macromols. Current approaches that utilize cyclic olefin feedstocks suffer from poor functional group tolerance, low initiator stability, and slow reaction kinetics. Improvements to current initiators will address these issues in order to develop more versatile and user-friendly technologies. Herein, we report a reinvigorated tethered ruthenium-benzylidene initiator, CB6, that utilizes design features from ubiquitous Grubbs-type initiators that are regularly applied in linear polymerizations We report the controlled synthesis of functionalized cyclic poly(norbornene)s and demonstrate that judicious ligand modifications not only greatly improve kinetics but also lead to enhanced initiator stability. Overall, CB6 is an adaptable platform for the study and application of cyclic macromols. via REMP. In addition to this study using Benzylidenebis(tricyclohexylphosphine)dichlororuthenium, there are many other studies that have used Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9SDS of cas: 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.SDS of cas: 172222-30-9
