Non-Covalent Immobilization of Rare Earth Heterobimetallic Frameworks and their Reactivity in an Asymmetric Michael Addition was written by Robinson, Jerome R.;Yadav, Jagjit;Fan, Xinyuan;Stanton, Gretchen R.;Schelter, Eric J.;Pericas, Miquel A.;Walsh, Patrick J.. And the article was included in Advanced Synthesis & Catalysis in 2014.SDS of cas: 66943-05-3 This article mentions the following:
Nonracemic rare earth binaphthalenediolate sodium complexes were immobilized on Merrifield resin by complexation with pyridinyl, amino, cyclen-, and aza-crown-functionalized Merrifield resins; the supported complexes were tried as recyclable catalysts for the enantioselective Michael addition of dibenzyl malonate to 2-cyclohexen-1-one. In the experiment, the researchers used many compounds, for example, 1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3SDS of cas: 66943-05-3).
1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3) belongs to ethers. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides. Ethers can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.SDS of cas: 66943-05-3
