This paper reports that tertiary α-azidyl phenyl ketones can be transformed into enamides by treatment with FeBr2 at elevated temperature in DMF. The reaction proceeds via 1,2-benzoyl migration from α-carbon to the nitrogen atom, accompanied by expulsion of a nitrogen molecule. This protocol is suitable for the synthesis of N-(cyclopent-1-en-1-yl)benzamides, N-(cyclohex-1-en-1-yl)benzamides, and N-benzoyl-α-methyl enamines and provides a convenient approach toward isoquinolones.

This work describes stereochemical results obtained for the preparation of α-bromomethyl ketones or α-bromoaldehydes starting from monocyclic and steroid cyclohexanones, using the Durst method.In all the cases studied here, the bromine is introduced selectively in the equatorial position.However, for monocyclic compounds, the yields of α-bromocarbonyl compounds are limited by the competitive formation of α-ethylenic carbonyl compounds.
