摘要

As mentioned above, the palladium-catalyzed cyclocarbonylation of alkynes with 2-iodophenol has been well established. Thus, the use of Co 2 Rh 2 nanoparticles was considered to be somewhat unusual at first. However, our preliminary experiment showed that Co 2 Rh 2 nanoparticles could be used to catalyze this reaction (Scheme [1] ). Therefore, we carried out an investigation to find an optimized set of reaction conditions. The reaction parameters such as bases and CO ...
