Development of catalytic formation of molecular skeletons using cobalt oxide supported gold nanoparticles

氧化钴负载的金纳米粒子在合成气(一氧化碳和氢气的混合物)气氛中有效地提供了钴的活性物种。该钴物种可作为传统的钴基化合物的替代试剂。以氧化钴负载的金纳米粒子为载体，顺利地进行了Pauson-Khandd反应、烷氧羰基化反应以及与炔烃形成钴配合物的反应。

Cobalt oxide supported gold nanoparticles have been revealed to effectively provide a cobalt active species under syngas (a mixture of carbon monoxide and hydrogen) atmosphere. This cobalt species could be used as an alternative reagent for the traditional cobalt carbonyls. The Pauson?Khand reaction, the alkoxycarbonylation, and the formation of cobalt complex with alkynes smoothly proceeded by using cobalt oxide supported gold nanoparticles.
