Camphor (1) was anodically oxidized at Pb/PbO2 and Pt in 1M H2SO4 (50 Vol.% MeCN). 1,2-campholide (4) as the main product was obtained with material yields up to 96% and current efficiencies up to 39% at the PbO2 anode. The most important side products were oxygen and 1,8,8-trimethyl-2-oxa-bicyclo[3.3.0]octan-3-one (5). A quantitative conversion of 4 to 5 is possible in strong acids. The effects of current densities and concentrations were studied in detail.
