2,4,4,6-Tetrabromocyclohexa-2,4-dienone: a new electron acceptor in the photosensitized oxidation of unsaturated substrates
Abstract
2,4,4,6-Tetrabromocyclohexa-2-4-dienone, usually used as a mild and selective brominating agent, acts as an electron acceptor in the sensitized photo-oxygenation of several unsaturated substrates; a mechanism is proposed.
