ChemInform Abstract
In the presence of the free-radical chain inhibitor DBMP, the thermolysis of (I) leads to the amine (III). Its yield increases up to 44%, when DBMP is absent, or diminishes, when the concentration of (I) increases. No azobenzene (II) is found. It is concluded that the species responsible for the induced decomposition is not the arylnitrene but a solvent-derived free radical (first-order rate constants for the pyrolysis of (IV) in the presence of DBMP; no neighboring group effect).
