The gas-phase photolysis of CD3COCD3 was investigated in the presence of CH3HgCH3 from 376 to 453 deg K. From the isotopic distributions of the methane and ethane fractions, evidence was obtained for the occurrence of the reaction: CD3 + CH3HgCH3 → CD3 HgCH3+ CH3 (Eact = 12.6 kcal/mole). The reaction is also postulated to occur in the liquid-phase photolysis of dimethylmercury. From the isotopic distribution of the ethane produced in the liquid- and solid-phase photolysis of CH3HgCH3-CD3HgCD3 mixtures, it was concluded that cage recombination of methyl radicals does take place. Contrary to previous conclusions, no evidence could be obtained for hot methyl radical effects in the liquid-phase photolysis of dimethylmercury.
