The reactivity of several transition-metal complexes toward liquid CO2 has been investigated as a means of screening such complexes for their ability to bind CO2. Although the known Ni(CO2)(PCy3)2 complex was prepared by the reaction of [Ni(PCy3)2]2(μ-N2) with CO2(l), the compounds Pd(PCy3)2 and Pt(PCy3)2 do not react with CO2(1) to afford CO2 complexes. But the compound Pt(PCy3)2 does react with wet CO2 to afford PtH(O2COH)(PCy3)2, a bicarbonato complex. Similar reactivity was seen for W(CO)3(PCy3)2, which produces WH(O2COH)(CO)3(PCy3)2 in wet CO2(l). The compounds Na[Co(N2)(PEt2Ph)3] and [Co(PEt2Ph)3]2(μ-N2) react with CO2(l) to form complexes that contain carbonyl and carbonato ligands. Peroxocarbonato complexes, IrR(OCO3)(CO)(PPh3)2 (R = Me, Ph), were prepared from IrR(O2)(CO)(PPh3)2 with CO2(l).
