In 2022,Sui, Xuelin; Gutekunst, Will R. published an article in ACS Macro Letters. The title of the article was 《Cascade Alternating Metathesis Cyclopolymerization of Diynes and Dihydrofuran》.Reference of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium The author mentioned the following in the article:
Ruthenium alkoxymethylidene complexes have recently come into view as competent species for metathesis copolymerization reactions when coupled with appropriate comonomer targets. Here, we explore the ability of Fischer-type carbenes to participate in cascade alternating metathesis cyclopolymn. (CAMC) through facile terminal alkyne addition The combination of diyne monomers and an equal feed ratio of low-strain dihydrofuran leads to a controlled chain-growth copolymerization with high degrees of alternation (>97% alternating diads) and produces degradable polymer materials with low dispersities and targetable mol. weights When combined with enyne monomers, this method is amenable to the synthesis of alternating diblock copolymers that can be fully degraded to short oligomer fragments under aqueous acidic conditions. This work furthers the potential for the generation of functional metathesis materials via Fischer-type ruthenium alkylidenes.Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9Reference of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium) 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.Reference of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium
