The Formation of Ketones by a Reaction Equivalent to R- + R'COCH2+ -> R'COCH2R

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