  title={Method for selective hydrogenodeshalogenation},
  author={Roland Jacquot and Georges Cordier},
The invention concerns a selective hydrodehalogenation method characterised in that it comprises a step which consists in contacting a substrate including a sp hybridisation carbon atom bearing an electro-attracting group and at least a fluorine atom, and a halogen atom heavier than fluorine, with a reagent comprising: an aqueous phase, a base, a group VIII metal as hydrogenation catalyst, and hydrogen dissolved in the aqueous phase, at a concentration in equilibrium with a gas phase whereof… CONTINUE READING
