“…Complexes of N -aryl β-diketiminates have shown great reactivity and selectivity for a variety of methodologies, 4, 5 including polymerization and functionalization of alkenes and cross-coupling reactions. In addition, late transition metal β-diketiminate complexes have been used to build low coordinate metal centers, mimicking the active sites of metalloproteins.…”

β-Diketiminates are widely used supporting ligands for building a range of metal complexes with different oxidation states, structures, and reactivities. This Perspective summarizes the steric and electronic influences of ligand substituents on these complexes, with an eye toward informing the design of new complexes with optimized properties. The backbone and N-aryl substituents can give significant steric effects on structure, reactivity and selectivity of reactions. The electron density on the metal can be tuned by installation of electron withdrawing or donating groups on the β-diketiminate ligand as well. Examples are shown from throughout the transition metal series to demonstrate different types of effects attributable to systematic variation of β-diketiminate ligands.

“…15,16 However, in sharp contrast to β-ketiminato (1−) ligands, the non-innocent formazanido(1−) ligand can be reversibly reduced to the complex-stabilized radical dianionic (2−) state, e.g., in the zinc complex shown in Scheme 4. 7,[17][18][19][20] Next to the abovementioned boron compounds, the only other well characterized main group element formazanido complexes described so far are some structurally characterized alkali metal formazanides.…”

“…Scheme 5 An example of Ln(AlMe 4 ) 3 as a starting material for the synthesis of rare earth pincer complexes β-Diketiminate (NacNac) ligands are particularly popular auxiliaries that can form complexes with metals spanning the periodic table [17,18]. Hence, numerous rare earth β-diketiminates have been prepared, some of which exhibit interesting reactivity patterns that produce pincer-type complexes relevant to this review.…”

The research field surrounding rare earth pincer complexes has reached a stage where a comprehensive review about the reactivity and catalytic behavior of these species is justified. In this contribution, we begin with a brief introduction on common strategies for the preparation of rare earth pincer complexes, continuing with a section devoted to the versatile reactivity observed for this class of compound. Thereafter, several types of compounds are discussed, including extremely reactive hydrides, cationic species, and intriguing scandium imido complexes. Finally, the last portion of this chapter sums up the hitherto reported catalytic studies, including discussions on ring-opening polymerization of cyclic esters, polymerization of olefins and hydroamination reactions, as well as several examples of more infrequently encountered catalytic processes.
