Abstract
Reactions of uranyl halides (UO sub 2 X sub 2) with hydrocarbyl anions of the type (R=Ar sup - or Ar sub n H sub 3 sub - sub n C sup -), result in the formation of thermally unstable intermediates ([UO sub 2 R sub 2 X sub 2] sup - sup 2) which undergo thermolysis to give uranium dioxide and organic products. The type of organic product obtained depends on the thermolysis pathway of the intermediate. If the intermediate thermolysis occurs via H-abstraction, the monomer RH is formed, and if thermolysis occurs via reductive elimination (coupling) the dimer R-R is obtained. The thermolysis pathways, the yield of organic products, and the type of these products are discussed on the basis of electronic and steric factors. When the hydrocarbyl group used is benzilic, the main factor that controls reactivity is found to be electronic. On the other hand, the steric factor is the main factor that controls the reactivity in the case of phenolic type hydrocarbyls. Differences in reactivity between uranyl chloride and uranyl bromide towards hydrocarbyl anions are discussed. 25 refs., 2 figs., 3 tabs. (A.M.H.).
