METHOD FOR PREPARING AROMATIC KETONE COMPOUNDS

摘要

The invention concerns a method for making aromatic ketone compounds and more particularly for preparing 1-[2'-methoxynaphth-6'-yl]but-2en-3-one which is an intermediate product useful for preparing 1-[2'-methoxynaphth-6'-yl]butan-3-one. The method for preparing an aromatic ketone compound from an aromatic compound bearing two halogen atoms and a donor group located in ortho position of one of the halogen atoms is characterised in that it consists in reacting said compound with an alpha -ketoolefin, in the presence of hydrogen and in the presence of a base and a catalyst comprising at least an element of group VIII of the periodic table of the elements, said element being complexed with at least an agent of co-ordination or a ligand.
