Abstract
The invention concerns a method for preparing a benzylic-type ether from an aromatic compound. The inventive method for preparing a benzylic-type ether from an aromatic compound is characterised in that it consists in: in a first step, acylating an aromatic compound by reacting said aromatic compound with an acylating agent, in the presence of an efficient amount of zeolite or a Friedel-Crafts catalyst leading to a ketonic compound; in a second step, reducing the carbonyl group into carbinol leading to a benzylic alcohol; in a third step, etherifying the hydroxyl group, by reacting the benzylic alcohol with another alcohol, in the presence of an efficient amount of zeolite.

A process for preparing a benzyl ether compound from an aromatic compound, consisting of:
- in a first step, acylating an aromatic compound by reacting said aromatic compound with an acylation agent in the presence of an effective quantity of a
- zeolite or a Friedel-Crafts catalyst to produce a ketone compound comprising a carbonyl group,
- in a second step, reducing the carbonyl group to a carbinol group, to produce a benzyl alcohol compound comprising a hydroxyl group, and then
- in a third step, etherifying the hydroxyl group by reacting the benzyl alcohol compound with a further alcohol in the presence of a effective quantity of a zeolite.
