A comparative study of the reactivity of the α-methylene groups of various types of ketones towards nitrous acid has been carried out and an attempt made to explain the results so obtained on a basis of the electronic arrangement of the compounds concerned. A number of α-diketones have been prepared by hydrolysis of the isonitroso- ketones (monoximes of diketones) by means of nitrous acid. One new diketone, acetyl valeryl was isolated and several derivatives were prepared. Diphenyl triketone was prepared in excellent yield by hydrolysis of isonitroso dibenzoyl methane with nitrous acid. An attempt to prepare ninhydrin by hydrolysis of the ß-oxime of 1:3 diketohydrindene with nitrous acid was unsuccessful the oxime being disrupted to give phthalic acid.
