Abstract
A novel rhodium-catalyzed linear codimerization of alkyl phenyl ketenes with internal alkynes to dienones and a novel synthesis of furans by an unusual cycloaddition of diaryl ketenes with internal alkynes have been developed. These reactions proceed smoothly with the same rhodium catalyst, RhCl(PPh(3))(3), and are highly dependent on the structure and reactivity of the starting ketenes.
摘要
开发了一种新型铑催化的烷基苯基烯酮与内部炔烃的线性偶联反应，生成二烯酮，以及一种新型的二芳基烯酮与内部炔烃的非同寻常的环加成反应，合成呋喃。这些反应在相同的铑催化剂 RhCl(PPh(3))(3)的作用下顺利进行，并且高度依赖于起始烯酮的结构和反应性。
