The ligated carbonate ion is easily released by the treatment with aqueous base. Thus, the reaction of complex 3 (5mM) in acetonitrile with 0.1 N NaOH aqueous solution afforded the complex 2, bis(hydroxy) Ni(II) complex quantitatively and instantaneously [9]. Half of the complex 3 was converted to complex 2 within a minute by the addition of 0.01 N NaOH aqueous solution to the 5mM complex 3 in acetonitrile [9]. As the complex 2 can reacts with CO2 and formed carbonato complex 3 can release the carbonate ion in the presence of aqueous base, it is expected that the catalytic CO2 hydration system can be developed by use of complex 2. 

Catalytic CO Oxidation by Free Au2. The potential catal3dic activity of Au2 in the CO combustion reaction was first predicted by Hakkinen and Land-man [382]. The subsequent experimental investigation employing an rf-ion trap indeed revealed the catalytic reaction of the gold dimer and, in conjunction with theory, a detailed reaction cycle could be formulated [33]. Also for particular larger gold cluster anions evidence for catalytic CO2 formation has... 

The keto-enol conversion on aluminum porphyrin is applied to catalytic CO2 fixation forming malonate species (102). Photo-irradiation of benzene solutions containing methacrylic esters or methacrylonitrile, (TPP)AlEt, and diethylzinc under CO2 catalytically produces the malonate species. The catalytic cycle of Scheme 8 is composed of three elementary reactions generation of aluminum enolate by 1,4-addition... 

There are many examples of successful cycloaddition of cyclopentenes, cyclopentadienes, dihydrofurans, and related mono- and polycyclic five-membered ring substrates. Several give better results in the presence of excess acetylene and catalytic Co2(CO)g than thqr do under stoichiometric conditions [Eq. (44)] [104].
