electrochemical approach in promoting directed C–H alkynylation with terminal alkyne via iridium catalysis is reported. This work employed anodic oxidation of Ir(III) intermediate (characterized by X-ray crystallography) to promote reductive elimination, giving the desired coupling products in good yields (up to 95%) without the addition of any other external oxidants. This transformation is suitable for various
报道了一种通过铱催化促进末端炔烃与末端炔烃的定向 C-H 炔基化的电化学方法。这项工作采用 Ir(III) 中间体(以 X 射线晶体学为特征)的阳极氧化来促进还原消除,在不添加任何其他外部氧化剂的情况下,以良好的产率(高达 95%)获得所需的偶联产物。这种转变适用于以 H2 为唯一副产物的各种定向基团,这保证了在温和条件下的高原子经济性和实际的氧化 C-C 键形成。
