, p. 4161 - 4164 (1994)
It has been found in this study that an acyl radical is formed by the reaction of an aldehyde with a radical NO3· generated by the anodic oxidation of NO3- and the reaction of this acyl radical with activated olefins lead to the formation of a diacylated compound.

(η3-1- and 2-Trimethylsiloxyallyl)Fe(CO)2NO complexes were prepared by the reaction of the corresponding siloxyallylic halides with Bu4N.These complexes reacted with both of carbon nucleophiles and carbon electrophiles preferentially at the less hindered sites of the allylic ligands.In these reactions, (η3-1-trimethylsiloxyallyl)Fe(CO)2NO complexes served as synthetically equivalent synthons for both of β-acyl carbocations and β-acyl carbanions and (η3-2-trimethylsiloxyallyl)Fe(CO)2NO complexes as both of α-acyl carbocations and α-acyl carbanions.The stereochemical courses of the reactions are described.

Anoxic oxidation of carboxylic acids with β-dioxolane substituents leads to good yields of symmetrical γ-bisdioxolanes.Hydrolysis of these compounds easily provides the corresponding γ-diketones.The synthesis of the starting acids is described.
Oxydation anodique de β-cetocarboxylates en milieu aqueux ou hydroorganique. Application a la synthese de γ-dicetones, de cetones ethyleniques et de cetoamides
Chkir, Moncef,Lelandais, Daniel,Bacquet, Cathy
, p. 945 - 951 (2007/10/02)
A systematic study of the anodic oxidation of β-ketocarboxylate anions in aqueous or hydroorganic solvents allows to distinguish the factors directing this reaction.Thus, it is possible by the appropriate choice of reaction medium and structure of the starting ion to synthesize products such as γ diketones, ethylenic ketones and ketoamides.
