Online resources: Abstract: Metal–metal bonded Rh2 and Ru2 complexes having a paddlewheel-type structure are exceptional catalysts for a broad range of organic transformations. I review here the recent efforts towards the observation and characterization of intermediates in these reactions that have previously eluded detection. Specifically, mechanistic investigations of carbenoid and nitrenoid reactions of Rh2(II,II)-tetracarboxylate compounds have led to the observation of a metastable Rh2(II,II) carbene complex as well as a mixed-valent Rh2(II,III)-amido intermediate. Related Ru2 nitrido compounds have been studied and found to undergo intramolecular C–H amination reactions as well as intermolecular reaction with triphenylphosphine.
