Co2 Transformation

A Cu-conjugated microporous polymer catalyst (CMP-Cu) was designed and prepared via Sonogashira-Hagihara cross-coupling of 3,8-dibromo-1,10-phenanthroline with 1,3,5-triethyny benzene in toluene. The CMP-Cu showed a catalytic activity for direct carboxylation of terminal alkynes with CO2 in the presence of K2CO3/Cs2CO3 at mild conditions. Several propiolic acids (such as 3-phenylpropiolic acid, 3-(4-nitrophenyl)propiolic acid and 4,4-dimethyl-2-pentynoic acid) have been prepared in a simple and feasible method at room temperature and atmospheric pressure. This catalyst is attractive for CO2 transformation.

Environmentally Friendly Process

A series of symmetrical 1,4-disubstituted buta-1,3-diynes is prepared with excellent yields (up to 95%) through homocoupling of terminal alkynes catalyzed by a copper salt under solvent-free conditions. This method provides an environmentally friendly process to prepare 1,3-diynes in short reaction times under mild conditions. Furthermore, the method is suitable for a wide substrate scope and has excellent functional group compatibility. The reaction can also be scaled up to gram level.
