Chemistry of diazadiene type ligands with extra coordination groups. Prospects of reactivity

Abstract N=C–C=N backbone ligands have been extensively studied for s-, p-, d- and f-block elements over the last several decades. Their diverse bonding modes and redox active properties have attracted a great deal attention and rendered them as one of the privilege ligands in coordination chemistry and catalysis. The review is focused on features of coordination behavior of DAD extended with different functional groups. The basic coordination modes, including reactions with various nucleophilic reagents, have been analyzed in detail. Synthetic and electrochemical aspects are also included.
