Co/Rh (Co:Rh = 2:2) heterobimetallic nanoparticles derived from Co(2)Rh(2)(CO)(12) react with alkynes and alpha,beta-unsaturated aldehydes such as acrolein, crotonaldehyde, and cinnamic aldehyde and release products resulting from [2 + 2 + 1]cycloaddition of alkyne, carbon monoxide, and alkene. alpha,beta-Unsaturated aldehydes act as a CO and alkene source. These reactions produce 2-substituted cyclopentenones.
源自Co(2)Rh(2)(CO)(12)的Co/Rh(Co:Rh = 2:2)异质双金属纳米颗粒与炔烃以及α,β-不饱和醛(如丙烯醛、巴豆醛和肉桂醛)发生反应,并释放出炔烃、一氧化碳和烯烃经[2 + 2 + 1]环加成反应生成的产物。α,β-不饱和醛充当一氧化碳和烯烃的来源。这些反应生成2-取代环戊烯酮。
