摘要
At room temperature, the early/late heterobimetallic complex Co((i)Pr(2)PNMes)(3)Zr(THF). has been shown to oxidatively add CO2, generating (OC)Co((i)Pr(2)PNMes)(2) (mu-O)Zr((i)Pr(2)PNMes). This compound can be further reduced under varying conditions to generate either the Zr oxoanion (THF)(3)Na-O-Zr(MesNP(i)Pr(2))(3)Co(CO) or the Zr carbonate complex (THF)(4)Na-2(CO3)-Zr(MesNP(i)Pr(2))(3) Co (CO). Additionally, reactivity of the CO2-derived product has been observed with PhSiH3 to generate the Co-hydride/Zr-siloxide product (OC)(H)Co((i)Pr(2)PNMes)(3)ZrOSiH2Ph.
