Reductive activation of O 2 by H 2 with rhodium terpyridine complexes in H 2O and CH 3CN is described and the mechanism is fully elucidated. The rhodium complex extracts electrons from H 2 and reductively activates O 2 to form a peroxo active intermediate. This intermediate is able to oxidise triphenyl phosphine to triphenyl phosphine oxide. A model system constructed in CH 3CN provides isolable analogues of catalytic intermediates in H 2O, allowing a detailed look at each step in the catalytic cycle.
