Abstract:
1. A process for the preparation of compounds (I) wherein M is, identically or differently on each occurrence, Rh, Ir, Pd or Pt; Z is, identically or differently on each occurrence, N or P; A, A′ is, identically or differently on each occurrence, N, C—H or C—R or C—R′; or alternatively two adjacent ring atoms A-A or A′-A′ on each occurrence, identically or differently, stand for S, O, Se or N—R R, R′ is, identically or differently on each occurrence, F, Cl, Br, NO R n is 1 for M=Pd or Pt and is 2 for M=Rh or Ir; which comprises reacting a compound (Ia)  wherein Y is on each occurrence, identically or differently, F, Cl, Br, I, OR and the other symbols and indices are as defined for compound (I), with an organometallic compound (Ib)  where Q stands for an alkali metal, an alkaline-earth metal or alkaline-earth metal halide, trialkyltin or zinc or a zinc halide, which may optionally also be substituted by further organic groups, and the other symbols and indices have the meaning given for compound (I).
