Patent ID: 7557248

Claim:
A method of creating a carbon-heteroatom bond by reacting a leaving group-bearing unsaturated compound and a nucleophilic compound introducing a heteroatom which can substitute for the leaving group, thereby creating a carbon-heteroatom bond, in the presence of a palladium-based catalyst, said reaction taking place in the presence of an effective amount of a metal hydroxide or ammonium hydroxide, with an alcohol solvent, wherein said leaving group-bearing unsaturated compound is an aromatic compound subsequently referred to as “haloaromatic compound” and that can be represented by formula (IIc): wherein: D is a benzene ring, R 23 , which is identical or different, represent substituents on the ring, Y represents a leaving group, n″ represents the number of substituents on the ring, and wherein said nucleophilic compound is a hydrazone.
