Microemulsions made from water, oil and surfactant are attractive alternatives to organic solvents for mediated electrochem. synthesis. Cyclization of 2-(4-bromobutyl)-2-cyclohexen-1-one (1) to 1-decalone (2) mediated by an electrochem. generated cobalt(I) complex favored the trans- form over cis-1-decalone by ∼93:7 in microemulsions, but poorer stereoselectivity was obtained in organic solvents. Microemulsion composition, surfactant type (cationic or anionic), or chirality of the mediator did not significantly influence the trans/cis ratio of 1-decalone. Selective formation of trans-1-decalone in microemulsions is attributed to equilibration of isomers via keto-enol tautomerization catalyzed by hydroxide ions formed by coelectrolysis of water during the reaction. Trans-1-decalone was efficiently produced in 2 h electrolyzes in microemulsions with large volume fractions of water. Organic solvents with trace amounts of water gave little stereoselectivity in similar periods, but longer equilibration times produced larger proportions of trans-1-decalone. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Recommanded Product: 112-59-4).
2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Recommanded Product: 112-59-4
