Improved process for the catalytic synthesis of diaryl ethers |
| abstract |
Described is a process for preparing diaryl ethers of the formula (I) n Ar-O-Ar'(I) In which Ar is an aryl or substituted aryl group and Ar' is an aryl, substituted aryl, heteroaryl or substituted heteroaryl group, nby reacting an aryl of formula (II) or a aryloxy salt of formula (III) n Ar-OH(II) n Ar-OR(III) In which Ar has the same meaning as in formula (I) and R is an alkali metal, nwith an aryl or heteroaryl bromide of formula (IV) n Ar'-Br(IV) nIn which Ar' has the same meaning as in formula (I), ncharacterized in that the reaction is carried out in the presence of a copper(I)salt and a 1-substituted imidazole as catalyst system. |
