ABSTRACT:
Ethers of aromatic acids are produced from halogenated aromatic acids in a reaction mixture containing a halogenated aromatic acid such as is described by the structure of Formula IIwherein each X is independently Cl, Br or I; the reaction mixture further comprising;(i) a polar protic solvent, a polar aprotic solvent or an alcoholic solvent containing the alcoholate RO-M+ (wherein M is Na or K), wherein the polar protic solvent, polar aprotic solvent or alcoholic solvent is either ROH or is a solvent that is less acidic than ROH;(ii) a copper (I) or copper (II) source; and(iii) an amino acid ligand that coordinates to copper, wherein the ligand comprises an amino acid in which the amine nitrogen and the carboxyl carbon are separated by no more than two carbon atoms.
