Alkenes made easy: In a complement to coupling processes of terminal alkynes, the reductive coupling of enones and allenes provides access to conjugate addition products that possess a 1,1‐disubstituted alkene (see scheme; cod=1,5‐cyclooctadiene). The solvent composition and reducing agent must be carefully matched to allow high levels of regioselectivity to be observed.
使烯烃变得容易:作为末端炔烃偶联过程的补充,烯酮和丙二烯的还原偶联可提供具有1,1-二取代烯烃的共轭加成产物(参见方案; cod = 1,5-环辛二烯)。溶剂组成和还原剂必须仔细匹配,以观察到高水平的区域选择性。
