氢氧化铯催化下,四氢呋喃作溶剂,室温、氮气保护下,炔基硫醚与硒酚发生亲核加成反应,立体选择性合成一系列(Z)-1-芳硫基-2-芳硒基烯,收率70%～93%.反应机理为氢氧化铯与硒酚反应产生的芳硒化铯,随后对炔硫醚进行亲核加成,形成的烯基负离子水解得到产物. Under the catalysis of cesium hydroxide, tetrahydrofuran was used as a solvent. At room temperature, a series of (Z) -1-arylthio-2-aryl selenides Alkylenes, the yield is 70% -93% .The reaction mechanism is cesium arylselenide produced by the reaction of cesium hydroxide with selenophenol followed by nucleophilic addition of alkyne sulfide to form the product of the alkenyl anion hydrolysis.
