1. Process for the preparation of the compounds of the formulae (1) to (32) and (1a) to (8a):
       M denotes Rh, Ir;
Y denotes O, S, Se, NR1;
Z is equal to F, Cl, Br, I, O-R1, S-R1, N(R1)2;
R is, identically or differently on each occurrence, H, F, Cl, Br, CN, a straight-chain or branched or cyclic alkyl or alkoxy
group having from 1 to 20 C atoms, where one or more non-adjacent CH2 groups may be replaced by —O—, —SiR12—, —S—, —NR1— or —CONR1— and where one or more H atoms may be replaced by F, or an aryl or heteroaryl group having 4 to 14 C atoms, which may be
substituted by one or more non-aromatic radicals R, where a plurality of substituents R, both on the same ring and also on
the two different rings, may together in turn define a further aliphatic or aromatic, mono- or polycyclic ring system;
T is, identically or differently on each occurrence, F, Cl, Br, CN, a straight-chain or branched or cyclic alkyl or alkoxy
group having from 1 to 20 C atoms, where one or more non-adjacent CH2 groups may be replaced by —O—, —SiR12—, —S—, —NR1— or —CONR1— and where one or more H atoms may be replaced by F, or an aryl or heteroaryl group having 4 to 14 C atoms, which may be
substituted by one or more non-aromatic radicals R, where a plurality of substituents R, both on the same ring and also on
the two different rings, may together in turn define a further aliphatic or aromatic, mono- or polycyclic ring system;
R1 is, identically or differently on each occurrence, H or an aliphatic or aromatic hydrocarbon radical having 1 to 20 C atoms;
L1 is a neutral, monodentate ligand;
L2 is a monoanionic, monodentate ligand;
L3 is a neutral or mono- or dianionic bidentate ligand;
a is 0, 1, 2, 3, or 4;
b is 0, 1, 2, or 3;
c is 0, 1, or 2;
m is 1 or 2;
n is 1, 2 or 3;
p is 1 or 2;
q is 0, 1 or 2;
by reaction of compounds (33) to (64) with a nitrating agent:
