treatment of cobalt oxide supported gold nanoparticles (Au/Co3O4) under syngas atmosphere effectively generated a cobalt carbonyl-like active species in the reaction vessel. The preparation of Au/Co3O4 was quite simple and the in situ generated cobalt species could be used as a stable and easy handling alternative for dicobaltoctacarbonyl without bothersome purification prior to use. The reactions, which
在合成气气氛下处理氧化钴负载的金纳米颗粒(Au / Co 3 O 4)可在反应容器中有效生成羰基钴样活性物质。Au / Co 3 O 4的制备非常简单,原位生成的钴物种可以用作八羰基二钴的稳定且易于处理的替代品,而无需在使用前进行麻烦的纯化。该反应对二钴八羰基化合物的纯度敏感,例如环氧化物的烷氧羰基化反应和Pauson-Khand反应,随着Au / Co 3 O 4顺利进行。
