Abstract
The subject of the invention is the process for the preparation of mixed ethers of general formula (I), wherein Ar represents an alicyclic, aromatic or one or more heteroatom-containing heterocyclic moiety, optionally substituted by one or more C1-4 alkoxy, methylenedioxy, C1-4alkyl, halogen, C1-4haloalkyl or nitro-group, and/or condensed with a benzene ring; R<1> means hydrogen, C1-4 alkyl, C1-4 haloalkyl, C2-4 alkenyl, phenyl, substituted phenyl, C3-6cycloalkyl group; R<2> means C1-6alkyl, C3-6alkenyl, or C3-6alkinyl group, optionally mono- or poly-substituted by C1-6alkyl, C1-6alkoxy, C3-6alkenyl, C3-6alkinyl, C1-6haloalkyl group or by halogen atom; or a C1-4 alkyloxy-C1-4alkyl-oxy-C1-4alkyl group. n = 1,2 by the reaction of compounds of general formula (II), wherein R<1> and n have the same meaning as above; X means hydroxy, halogen or sulfonester leaving group, with the compounds of the general formula (III): R2-Y, wherein R<2> has the same meaning as above; Y means hydroxy, halogen or sulfonester leaving group, with the proviso that one of the reaction partners of general formulae (II) and (III) is an alcohol, characterized by, that the reaction is performed under heterogenous conditions in presence of an aqueous base and a phase transfer catalyst, and the resulting product is optionally stabilized by the addition of a base and/or anti-oxidant.
