Article abstract of DOI:10.1039/DT9810002585

Reactions of (bipy=2,2'-bipyridyl; L=PPh3, PMePh2, PBuⁿ3, or PEt3) with O2 alone in dimethylformamide and SO2 plus O2 in dichloromethane lead to the formation of I2 and precipitation of Cu.The complex catalyses the oxidation of ethanol by dioxygen to acetaldehyde and H2O2 in the presence of equimolar quantities of Na.Added phosphine acts as a strong inhibitor and the catalytic decomposition of H2O2 by the complexes leads to their deactivation.A tentative reaction mechanism is discussed.
