摘要: Sonogashira cross-coupling reaction is significant for the formation of C―C bonds and the creation of new substance in organic synthesis, which is usually catalyzed using noble metal, such as palladium or non-precious metal, such as copper under harsh reaction conditions. Herein, we report the encapsulation of an organic dye(i.e., Eosin Y, EY) into a Cu(I) cyclic trinuclear unit(CTU) based covalent-metal organic framework(CMOF), namely EY@JNM-1, which demonstrates outstanding photocatalytic performance for the Sonogashira cross-coupling reaction of iodobenzene with alkynes. The EY@JNM-1 not only exhibited high catalytic activity for the alkynes(>99% conversion) and excellent selectivity for the cross-coupling product(>99%) under mild conditions, but also displayed excellent stability and recyclability.
