Abstract
Free Radical Reactions of N-Heterocyclic Compounds. XIII. Oxidation of Cyclic Hydrazo Compounds with 2,4,6-Tri-tert-butyl-phenoxy Radical and Reactions of Radical Combination Products N-Heterocyclic compounds 1a, b containing the hydrazo structure were oxidized with 2,4,6-tri-tert-butyl-phenoxy radical (2). It was shown that the oxidation did not lead to the azo compounds 5a, b, but rather to radical combination products 6a, b of 2 via the intermediate hydrazyls 4a, b. The decomposition of adducts 6a, b was found to be similar to the reaction of radical combination products of aryl hydrazyls and CH-acidic compounds. The main reactions consisted of cleavage to starting radicals or elimination of isobutene forming the respective phenolic compounds 13a–c.
