reaction of alcohols with benzylphosphine oxides to form alkenes in good yields. The protocol suits for a wide scope of substrates and generates only E-configurated alkenes. The method also shows good compatibility of functional groups. Methoxy, methylthio, trifluoromethyl, ketal, fluoro, chloro, bromo, thienyl, and furyl groups are tolerated. The mechanism studies support that the reaction proceeds through

噻吩基和
呋喃基均可接受。机理研究表明,该反应是通过醇催化脱氢生成醛或酮,然后在 KO t Bu 存在下与氧化苄基
二苯基膦缩合进行的。
