摘要：
Nitrogen-doped carbon-supported Co/Cu bimetallic catalysts were found to catalyze olefination of aldehydes with ethyl diazoacetate. In the presence of triaryl phosphine with electron-withdrawing groups, various aromatic aldehydes could be converted into unsaturated esters in good to high yields. The system is heterogeneous, allowing for recovery and reuse of the catalyst for several runs without significant loss of activity.
