Transfer of an oxide ion from an anionic carbon dioxide complex to a cationic carbonyl complex

Article abstract of DOI:10.1021/om00127a031

Reaction of Li₂[W(CO)₅(CO₂)] with [Fp(CO)]-BF₄ leads principally to [W(CO)₆] and [Fp₂]. It is proposed that Li[Fp(CO)₂] is the initial product, but that this reacts readily with [Fp(CO)]BF₄ to give [Fp₂], CO, and CO₂. Initial oxide transfer to [Fp(CO)]BF₄ is supported by labeling studies using ¹³CO₂ and C¹⁸O₂ which show that oxygen, but not carbon, is incorporated into the product [Fp₂] from the CO₂ of Li₂[W(CO)₅(CO₂)].
