WebBoth ethylene and diethyl ether are formed from ethanol dehydration under similar conditions. However, at a lower temperature, symmetrical ether (diethyl ether) is the major product. However, at a relatively higher temperature (180°C), the alkene is recovered as the major product. Ethers can also be prepared by Williamson synthesis. WebA nickel-catalyzed cross-electrophile coupling reaction between benzyl alcohols and aryl halides is mediated by a low-valent titanium reagent generated from TiCl 4 (2,6-lutidine) and manganese powder. The reaction afforded the cross-coupled product in high yield. T. Suga, Y. Ukaji, Org. Lett., 2024, 20, 7846-7850.
