The previously suggested scheme describing the formation of the thermolysis products 1c, 1d and 2 of N,N-dimethyl-2,2-diphenyl-2-(phenylazo)acetamide (1b) has been refined on the basis of deuterium tracer studies and the results of thermolysis experiments with compound 1b, carried out in 2,2-dimethoxypropane in the presence of sodium methoxide and acetone.The deuteration studies have revealed the ambident reactivity of (N,N-dimethylcarbamoyl)diphenylmethyl radicals(3) in hydrogen abstraction reactions, as a result of which the 1,4-cyclohexadiene 6 (and/or the isomeric 1,3-cyclohexadiene) derivatives may be formed, in addition to the fully aromatic isomer 1c, as the primary products of these reactions.

In contrast to earlier claim, the title reaction takes place by direct attack of hydride anion at the α-carbon atom of the substrate.EI induced fragmentation of N,N-dimethyl-2,2-diphenylacetamide takes place with complete H scrambling within the diphenylmethyl moiety.
