%X A general method has been developed for the overall transformation of &#945;- bromo ketones to &#945;-alkyl or &#945;-aryl ketones , with benzotriazole being used as a synthetic auxiliary. &#945;- Benzotriazolyl ketones , when converted into their phenylhydrazones, reacted smoothly with alkyl and aryl Grignard reagents, which displaced benzotriazolate, to give the corresponding &#945;-alkyl or &#945;-aryl hydrazones. In some cases, these hydrolysed directly to the &#945;-alkyl or &#945;-aryl ketones. In each case, the product was treated with 2,4-dinitrophenylhydrazine to isolate the target ketones as the corresponding 2,4-dinitrophenylhydrazones.
