In 2022,Yasir, Mohammad; Singh, Manvendra; Kilbinger, Andreas F. M. published an article in ACS Macro Letters. The title of the article was 《A Single Functionalization Agent for Heterotelechelic ROMP Polymers》.Reference of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium The author mentioned the following in the article:
Heterotelechelic polymers are an important class of materials finding applications in bioconjugation, imaging, sensing, and synthesis of organic/inorganic hybrid systems with interesting features. However, the synthesis of such polymers is challenging. Here, we report a mechanistically unique and most efficient method based on a single functionalization agent to prepare heterotelechelic polymers by a ring-opening metathesis polymerization Different functionalization agents can be synthesized in one simple step from inexpensive com. starting materials. The functionalization agents initially generate a functional initiator from com. Grubbs’ first-generation ruthenium benzylidene catalyst. During this process, a functional dihydrofuran derivative is produced. After functional initiation and propagation of a suitable monomer, the dihydrofuran derivative functionally terminates the polymerization yielding a primary alc.-terminated heterotelechelic polymer. Mol. weight control is achieved by varying the ratio between monomer and Grubbs’ first-generation catalyst. This method may emerge as a popular choice to prepare heterotelechelic polymers due to its simplicity and efficiency. The results came from multiple reactions, including the reaction of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9Reference of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium)
Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9) is the first metathesis catalyst to be widely used in organic synthesis. It is useful for acyclic diene metathesis polymerization (ADMET), Ring-Opening Metathesis Polymerization (ROMP) of strained cyclic olefins, ring opening metathesis (ROM), and so on.Reference of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium
