Abstract: 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
