A large number of complexes of the first-row transition metals with non-innocent ligands has been characterized in the last few years. The localization of the oxidation site in such complexes can lead to discrepancies when electrons can be removed either
Synthesis of highly hindered polyanionic chelating ligands

Practical and efficient protocols to obtain highly hindered polyanionic chelating ligands based on bis-(3,5-di-tert-butyl-2-hydroxybenzamido) compounds are reported here. N-3,5-di-tert-Butylsalicyloyloxysuccinimide was treated with aliphatic diamines to form aliphatic hydrocarbon-linked bis-amides 4a-4g. Aromatic diamines required more powerful electrophile, thus the corresponding benzylated acid chloride was used to form aromatic hydrocarbon-linked bis-amides 8a-8d. The yields ranged from good to very good and showed that choosing the right acylating agent is a key point in this synthesis. All the compounds were characterized by elemental analysis, IR, MS and NMR.
