The reaction was carried out by mixing equimolar quantities of the oxime ethers and pulverized N-bromosuccinimide in carbon tetrachloride. The mixture was heated at reflux with the introduction of radiant energy from an ultraviolet sun lamp (GE, 275 W). Preliminary work to determine optimum conditions was carried out utilizing butanone oxime 0-ethyl ether. It was found that heat alone was unsatisfactory since the reaction time was ...
