Molecular recognition between a water-soluble organometallic complex and a β-cyclodextrin: First example of second-sphere coordination adducts possessing a catalytic activity was written by Caron, Laurent;Bricout, Herve;Tilloy, Sebastien;Ponchel, Anne;Landy, David;Fourmentin, Sophie;Monflier, Eric. And the article was included in Advanced Synthesis & Catalysis in 2004.Safety of 4-Bromo-4′-tert-butylbiphenyl This article mentions the following:
Formation of stable second-sphere adducts between a water-soluble organometallic complex and a cyclodextrin (CD) is possible by finely designing the structure of the water-soluble phosphane. The key point to obtain such adducts was the synthesis of a water-soluble phosphane which possesses a tert-butylphenyl group recognized by the CD and separated from the phosphorus atom by a Ph ring to avoid phosphane decoordination during the mol. recognition process between the organometallic complex and the CD. These adducts are able to catalyze the cleavage of water-insoluble carbonate in a biphasic system. In the experiment, the researchers used many compounds, for example, 4-Bromo-4′-tert-butylbiphenyl (cas: 162258-89-1Safety of 4-Bromo-4′-tert-butylbiphenyl).
4-Bromo-4′-tert-butylbiphenyl (cas: 162258-89-1) belongs to organobromine compounds. Most of the natural organobromine compounds are produced by marine organisms, and several brominated metabolites with antibacterial, antitumor, antiviral, and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others. One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.Safety of 4-Bromo-4′-tert-butylbiphenyl
