Reactions of acetylenes derived from glyceraldehyde and propargyl aldehyde show remarkable reactivity in Kinugasa cycloaddition/rearrangement cascade process catalyzed by Cu(I) ion. Reactions proceed by formation of a rigid dinuclear copper(I) complex in which each copper ion is coordinated to one or both oxygen atoms in the acetylene molecule and to both triple bonds. It has been demonstrated that
衍生自甘油醛和炔丙基醛的乙炔的反应在Cu(I)离子催化的Kinugasa环加成/重排级联过程中显示出显着的反应性。反应通过形成刚性双核铜(I)配合物而进行,其中每个铜离子与乙炔分子中的一个或两个氧原子以及两个三键配位。已经证明,一个氧原子可以被苯环取代,该苯环能够通过芳族六聚体配位铜离子。还可以在催化量的铜盐存在下进行高产率的Kinugasa反应,以提供可接受的产率而不降低非对映选择性的产物。
