    摘要: The present invention relates to a process for converting an isomerically pure compound C1 of the formula I or a mixture M1 comprising C1 into an isomeric compound C2 of the formula I which is different from C1 or a mixture M2 comprising C2, where the variables have the following meanings: n is 2 or 3; M is Pd or Pt, in each case in the formal oxidation state +II, when n is 2; and is Ru, Os, Co, Rh or Ir, in each case in the formal oxidation state +III, when n is 3; Do is a donor atom selected from the group consisting of N, O, S and P; r is 1 when Do is N or P, and is 0 when Do is O or S; Y1, Y2 are each, independently of one another, hydrogen, alkyl, alkenyl, alkynyl, aryl, heteroaryl, alkyloxy, aryloxy, alkylthio, arylthio, alkylcarbonyl, arylcarbonyl, carboxyl, alkyloxycarbonyl, aryloxycarbonyl, hydroxysulfonyl, alkyloxysulfonyl, aryloxysulfonyl, halogen, CN, CHO, NO2 or NO, or Y1 and Y2 together with the carbon atom to which they are bound form a six-membered aromatic ring which may comprise one or two nitrogen atoms and may optionally be fused with a further, optionally fused and optionally hetero-atom-comprising ring; Y3 is alkyl, alkenyl, alkynyl, aryl or heteroaryl; A is a bridge having three or four atoms of which one or two atoms may be heteroatoms and the remaining atoms are carbon atoms, so that the group forms a five- or six-membered heteroaromatic ring or benzene ring which may optionally be substituted by substituents selected from the group consisting of alkyl, alkenyl, alkynyl, aryl, heteroaryl, alkyloxy, aryloxy, alkylthio, arylthio, alkylcarbonyl, arylcarbonyl, carboxyl, alkyloxycarbonyl, aryloxycarbonyl, hydroxysulfonyl, alkyloxysulfonyl, aryloxysulfonyl, halogen, CN, CHO, NO2 and NO and may optionally be fused with a further, optionally heteroatom-comprising ring which may likewise be fused and substituted by substituents selected from the group consisting of alkyl, alkenyl, alkynyl, aryl, heteroaryl, alkyloxy, aryloxy, alkylthio, arylthio, alkylcarbonyl, arylcarbonyl, carboxyl, alkyloxycarbonyl, aryloxycarbonyl, hydroxysulfonyl, alkyloxysulfonyl, aryloxysulfonyl, halogen, CN, CHO, NO2 and NO; which comprises allowing a Brönsted acid or a mixture of Brönsted acids to act on C1 or M1 in the presence of a solvent or solvent mixture at a temperature of from 0° C. to the boiling point of the solvent or the solvent mixture, with the proviso that a) the formation of C2 from C1 occurs under the conditions of the process and b) when both M1 and M2 are mixtures comprising C1 and C2, the respective isomer ratios of C1 and C2 in the mixtures M1 and M2 are different from one another.
