Frustrating ruthenium: The ruthenium complex 1 is shown to bind carbon dioxide or aldehyde in a manner similar to a frustrated Lewis pair. Compound 2 catalyzes the reduction of CO2 in the presence of pinacolborane (HBpin), yielding MeOBpin and O(Bpin)2 (see picture; Ru red, P orange, N green, O light red, C black).
