Title:
METHOD FOR PREPARING A POLYAROMATIC COMPOUND
Document Type and Number:
WIPO Patent Application WO2001038291
Kind Code:
A3
Abstract:
The invention concerns a method for preparing a polyaromatic compound comprising a chain of two aromatic cycles and bearing at least an amino group on one of the aromatic cycles. The inventive method is characterised in that it consists in reacting an aromatic compound bearing at least an amino group and a leaving group and an arylboronic acid, in an aqueous medium and in the presence of a palladium-based catalyst.
