In earlier reports we have describe d our efforts to understand the mechanism of deuterium incorporation during the thermolysis of 1,2-diphenylethane and 2,2,5,5-tetramethyl-3,4-diphenylhexane under D{sub 2} gas in a glass vessel. We have reported that in both of these cases, there is substantial deuterium incorporation. A summary of our conclusions follows: Conclusions previously reported for the 1,2-diphenylethane (DPE) system. 1. Benzyl radicals produced in the thermolysis react mainly with DPE to extract a hydrogen atom and produce undeuterated toluene. 2. The 1,2-diphenylethyl radicals produced are mainly responsible for the reaction with D{sub 2} to give D atoms. 3. D atoms then react with aromatic rings to form adduct radicals which are, at least in part, reconverted to D-substituted aromatics in termination steps. 4.2-Phenylethyl radicals react in a less discriminating manner, 1/3 to 1/2 of the events probably involving direct reaction with D{sub 2}. 5. A reasonable match to major product distribution can be accomplished using a model consisting of the set of ten reactions.
