摘　　要：开发了一种使用铜基固体废弃物代替传统铜盐参与Sonogashira和Glaser-Hay偶联反应的方法,在较为温和的条件下,高效地合成了多种二取代炔烃.对于Sonogashira偶联反应,各种取代的苯乙炔和碘代芳烃反应效果良好,以57%~97%的产率生成二芳基乙炔类化合物.对于Glaser-Hay偶联反应,多种末端炔烃既能以优秀的产率生成对称二取代1,3-丁二炔衍生物,也能以中等的产率合成交叉偶联产物.克级规模实验和循环实验表明该固体废弃物在有机合成中有潜在的应用前景.An approach to the Sonogashira and Glaser-Hay coupling reactions utilizing copper-based solid wastes instead of traditional copper salts has been developed.This method enables the efficient synthesis of various disubstituted alkynes under relatively mild conditions.For the Sonogashira coupling reaction,diverse substituted phenylacetylenes and aryl iodides exhibit excellent reactivity,resulting in diaryl acetylene compounds with yields ranging from 57%to 97%.The Glaser-Hay coupling reaction allows for the high-yield production of symmetrically disubstituted 1,3-butadiyne derivatives using a variety of terminal alkynes.Additionally,moderate yields can be achieved for cross-coupling products.Gram-scale and cycling experiments demonstrate promising prospects for the application of solid waste in organic synthesis.
