Bleach activating dendrimer ligands and their metal complexes

Es werden bleichaktive Dendrimer-Liganden der Formel (R R )N-X-N(R R ) und deren Metall-Komplexe beansprucht, wobei R und X die in der Beschreibung angegebenen Bedeutungen haben. Novel dendrimer ligand compounds and their complexes with transition metals are claimed. Dendrimer ligand compounds of formula (R R )N-X-N(R R ) (1) and their complexes with transition metals are claimed.
