  The rhenium eta(1)-C carboxylate Cp(PPh3)(NO)ReCO2- (1Li(+) or 1K(+)) undergoes an unusual reductive disproportionation sequence in the presence of excess CO2 that generates a new Re-2(u(2)-eta(3)-CO2) complex Cp(PPh3)(No)ReCO2Re(CO)(NO)(PPh3)(eta(1)-Cp) (2) plus CO32-. The overall stoichiometry entails 3 equiv of CO2 plus 2 equiv of Cp(PPh3)(NO)ReLi transforming to ligated CO2 and CO (i.e., 2) plus CO32-. Three procedures were used to generate 2: treating (a) Cp(PPh3)(NO)ReLi with excess CO2, (b) 1K(+) with excess CO2, and (c) 1K(+) with Cp(PPh3)(NO)Re(CO)BF4. The results of this study are consistent with the intermediacy of an undetected metalloanhydride Cp(PPh3)(NO)ReC(O)OC(O)Re(NO)(PPh3)Cp (8), which upon a subsequent eta(5)-eta(1) Cp ring shift on one rhenium center affords 2. This product undergoes different solvolysis reactions in the presence of methanol and triethylsilanol. The former gives 2 equiv of the methyl ester Cp(NO)(PPh3)ReCO2CH3 (6), whereas the latter replaces the eta(1)-Cp group with a silanolate to give the previously characterized Cp(PPh3)(NO)ReCO2Re(Co)(No)(PPh3)(OSiEt3) (5a).
