Abstract:The reaction of tetraphenylcyclopentadienone
with Co2(CO)8 generates the mixed-valence
tricobalt complex
[Ph4C4CO]Co(CO)2]2[μ-Co(MeCN)2]. In contrast
to the conventional Pauson–Khand reaction to generate cyclopentadienone-ligated
cobalt complexes, this method benefits from both mild reaction conditions
and high yields. Treatment of this tricobalt complex with proton sources
such as water or alcohols yields the monomeric hydroxytetraphenylcyclopentadienyl
cobalt complex [Ph4CpOH]Co(CO)2. Phosphite sub… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
