Acikalin, Hande; Ziegler, Felix; Wang, Dongren; Buchmeiser, Michael R. published an article in 2021. The article was titled 《A Hard Templating Approach to Functional Mesoporous Poly(norborn-2-ene)-Based Monolithic Supports》, and you may find the article in Macromolecular Chemistry and Physics.Reference of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium The information in the text is summarized as follows:
A hard-templating method is presented for the synthesis of functional ring-opening metathesis polymerization (ROMP) derived, poly(norborn-2-ene)-based monolithic supports prepared under solvent-induced phase separation conditions using the first-generation Grubbs initiator RuCl2(PCy3)2(CHPh) (1, Cy = cyclohexyl). Norborn-2-ene (NBE), 1,4,4a,5,8,8a-hexahydro-1,4,5,8-exo,endo-dimethanonaphthalene (DMN-H6) and trimethylolpropane-tris-(5-norbornene-2-yl-carboxylate (TMPTNC) are used as monomers and crosslinkers, resp. 2-Propanol and toluene are used as macro- and microporogen. Silica (SiO2) nanowires (SNWs) surface-modified with NBE are used as hard templates. exo,endo-Norborn-5-ene-2-ylmethanol (NBE-CH2OH) is used as functional comonomer. The tailored porogenic system together with the surface-functionalized SNWs allows for a full dispersion of the SNWs in the polymerization mixture and their incorporation into the monolithic structure during the phase separation process. This way, ROMP-derived monoliths with pore dimensions of 10-15 nm, sp. surface areas up to 3.7 m2 g-1, and pore porosities up to 33% are obtained after removal of the SNWs by chem. etching at room temperature The experimental part of the paper was very detailed, including the reaction process of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9Reference of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium)
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
