This causes an additional donor-acceptor interaction that the metal center in a corresponding metal complex can stabilize. It is particularly advantageous that the nucleophilicity of the metal center can be set by selecting the groups E1, E2 or E2 ', E3 or E3' and E4 (electron-donating or electron-withdrawing).
