Encapsulation of polyoxotungstate into dendrimers by ionic bonding and their use as oxidation catalyst was written by Jahier, Claire;Plault, Lauriane;Nlate, Sylvain. And the article was included in Israel Journal of Chemistry in 2009.Related Products of 10297-05-9 This article mentions the following:
A family of 36-armed dendrimers containing six internal amino groups was synthesized and used to incorporate polyoxometalates (POMs) into their structures by ionic bonding. Allyl-terminated dendrimer 17 (with oxidizable end groups) and methylphenyl-terminated dendrimer 18 (with non-oxidizable end groups) were used for these studies. It was found that the electrostatic incorporation of the tri-anionic POM [PO4{WO(O2)2}4]3- into the methylphenyl-terminated dendrimer 18, in an acidic medium, leads to the dendritic POM hybrid 19, bearing two POM units in its structure. In contrast, attempts to encapsulate POMs into allyl-terminated dendrimer 17 gave unsatisfactory results. Indeed, the epoxidation kinetics of the 36-olefinic terminated dendrimer 17 was too slow, and the expected 36-epoxy-dendritic POM framework 20 was not obtained. Lengthening the reaction up to six hours led to the decomposition of POM species. The solubility in organic solvents of the dendritic POM hybrid 19, combined with its NMR and IR data, indicate that POM units are clearly connected to the dendritic structure. The catalytic performance of this hybrid material in the oxidation of cyclooctene shows that the properties of POM are retained. The POM-encapsulated dendrimer 19 was found to be an effective catalyst in the oxidation of cyclooctene. In the experiment, the researchers used many compounds, for example, 1-Chloro-4-iodobutane (cas: 10297-05-9Related Products of 10297-05-9).
1-Chloro-4-iodobutane (cas: 10297-05-9) belongs to iodide derivatives. Organic iodides are widely used in organic synthesis. Halogenation of aromatic hydrocarbons is a very important reaction via an electrophilic aromatic substitution. A typical method for synthesis of aromatic iodides is diazotization of primary aromatic amines followed by treatment of potassium iodide. Aliphatic alcohols are converted to alkyl iodides by treating with hydrogen iodide.Related Products of 10297-05-9
