| Abstract: | Three alternative syntheses of 1,3,5,7-tetraiodotricyclo3.3.0.03,7]octane are described. Reaction of this tetraiodide with sodium amalgam in the presence of dienes or with molten sodium in boiling 1,4-dioxane in the absence of trapping agents led to very complex mixtures of products, presumably due to competitive 1,2- and 1,3-deiodination reactions. |
