Porous Vycor glass (PVG) impregnated with WO₃ photocatalyzes the conversion of CO₂ to CH₄, but requires ultraviolet light. Our investigations focus on the assembly of multicomponent sites in the glass matrix capable of carrying out this eight-electron reduction with visible light. To this end, we have begun to explore the synthesis of the bimetallic [(bpy)₂RudppW(CO)₄]²⁺, where dpp designates the bridging ligand 2,3-bis(2-pyridyl)pyrazine. Although dpp readily reacts with W(CO)₆ thermally and photochemically to form W(CO)₄dpp, the major obstacle to the synthesis of the bimetallic is the difference in solubilities of the two reactants. This presentation will describe the use of [Ru(bpy)₂dpp]²⁺-doped-PVG in hydrocarbon solutions of W(CO)₆ as a photochemical reaction system. Photolysis through the W(CO)₆ solution leads to spectroscopic evidence of the formation of [(bpy)₂RudppW(CO)₄]²⁺ in the hydrocarbon solution.
