EY@JNM-1 demonstrates high catalytic activity and excellent selectivity in the Sonogashira cross-coupling reaction, with outstanding stability and recyclability under mild conditions.
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.
