The rearrangement of light and deuterium-labelled cis- and trans-2-methyl-3-phenyloxiranes (1, 2 and 1, 2 ) was studied on ZnO, Al-O-j and WO, and in the presence of BF,. Both in the gas phase (473-673 K) and in the liquid phase (298-413 K), l-phenyl-2-propanone (3) and 2-phenylpropanal (4) were formed with high selectivities (0-90% and 11-80%, respectively). Ring-opening was found to occur by selective fission of the benzyl C-0 bond. Mechanistic studies revealed the formation of an open carbenium ion or a double-bonded surface intermediate. The acidic (electrophilic) and basic characters of the oxides determine the product distributions by affecting the relative importance of the competing mechanisms. 

Hydrolysis of 2-Methyl-2-benzyl-l,3-dioxolane. A sample of 1 gram of the dioxolane was suspended in 20 ml. of 50% dioxane which contained enough HC1 to make it 0.5N. The suspension was heated at 60°C. and became a clear solution in 1-2 minutes. Total heating time was 5 minutes. The product was identified as 3-phenyl-2-propanone by the properties of its 2,4-dinitrophenylhydrazone and semicarbazone derivatives.
