The photolysis of CH3CD2COCD2CH3 has been studied over a temperature range from 25°C. to 365°C. The results confirm several features of the mechanism, previously proposed for the photolysis of diethyl ketone. It is concluded that disproportionation of ethyl radicals occurs by a "head to tail" mechanism. As activation energy for the reactiona value E4 = 8.7 kcal. was found. As activation energy for

An improved method of preparing deuterated alkanes from the halides has been developed. Dehalogenation of ethyl iodide, 1,1-dibromoethane, and 1,1,1-trichloroethane with zinc dust in deuterium oxide – dioxane solutions, or even with deuterium oxide alone, gave excellent yields of ethane-d1, ethane-1,1-d2, and ethane-1,1,1-d3. Methane-d1, -d2, -d3, and -d4 were prepared similarly from methyl iodide
