Abstract

In this study, we discussed an efficient approach for the synthesis of camphorquinone from camphor by the continuous reaction of bromination and oxidation. The oxidation of 3-bromocamphor was catalyzed by Fe-porphyrins with air. The catalytic activity of iron-metallated functional porphyrins was investigated under optimization conditions. The results showed that this method was a milder alternative to the reported methods, with a simple, greener procedure in which the advantages were the utilization of air as the oxidant and the use of metalloporphyrins as catalysts.
