The photochem. of W2(CO)102- was studied with the goal of determining if irradiation of this dimer generates a powerful reducing agent, presumably a 19-electron species. In general, the photochem. of W2(CO)102- is comparable to that of other metal-metal-bonded carbony dimers. Irradiation into the low-energy tail of the d¦Ð ¡ú ¦Ò* electronic transition of W2(CO)102- led to W-W bond homolysis. The resulting 17-electron W(CO)5– radicals could be trapped with suitable ligands such as 4-cyanopyridine to give 19-electron adducts [adducts that form when 17-electron radicals react with 2-electron ligands]. Evidence is presented that PPh3 and PBu3 also react with photogenerated W(CO)5– to form adducts: W(CO)5– + PR3 ¡ú W(CO)5PR3–. These adducts are powerful reducing agents, and they were used to reduce CO2 to formate and CO. The only organometallic product formed in the reaction was W(CO)5PPh3, the oxidized form of the 19-electron complex. In a similar manner, Mn2(CO)10 was reduced to Mn(CO)5–, Cp2Co+ to Cp2Co, benzophenone to the radical anion, and methylviologen (MV2+) to MV+. Alternative reduction mechanisms involving the W(CO)5– radical, W(CO)52-, or HW2(CO)10– as reductants were shown not to be operating. Nineteen-electron complexes generated by irradiation of Cp2Mo2(CO)6 proved incapable of reducing CO2.
