SELECTIVE HYDRODEHALOGENATION METHOD

摘要

The invention concerns a selective hydrodehalogenation method characterised in that it comprises a step which consists in contacting a substrate including a sp<3> 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 the partial pressure in hydrogen is not less than 50kPa, advantageously ranging between 50kPa and 2.10<7> Pa. The invention is applicable to organic synthesis.
