- Electrocarboxylation de composes carbonyles aliphatiques, aromatiques et vinyliques: interet de l'utilisation d'une anode consommable en magnesium
-
In the presence of carbon dioxide in DMF, the electroreduction of carbonyl compounds or α,β-ketoalkenes at high concentration yields respectively α-hydroxyacids and β-ketoacids.The use of a sacrificial magnesium anode allows constant current electrolyses in a diaphragmless cell.

- REACTION OF METHYL-SUBSTITUTED 7-CHLORO- AND 7,7-DICHLOROBICYCLOheptan-2-ones WITH SODIUM METHOXIDE AND THIOPHENOLATE
-
The reaction of exo-7-chloro-6-methylbicycloheptan-2-one, exo-7-chloro-4,4,6-trimethylbicycloheptan-2-one, 7,7-dichloro-6-methylbicyclo-heptan-2-one, and 7,7-dichloro-4,4,6-trimethylbicycloheptan-2-one with sodium methoxide takes place with opening of the cyclopropane ring and the formation of the corresponding 3-dimethoxymethyl- and 3-trimethoxymethylcyclohexanones.The reaction with sodium thiophenolate leads to the product from substitution of the exo-chlorine atom by the phenylthio group with retention of the three-membered ring.
