Abstract
WE have found that ethylenes, for example, styrene, stilbene and triphenyl ethylene, react with 1,2-diketones when dissolved in benzene (thiophene-free) and exposed to sunlight. The experiments were carried out in 'Monax' glass tubes in an atmosphere of carbon dioxide. The reaction between phenanthraquinone and stilbene, which proceeds very rapidly, may be illustrated by the following scheme:
