“…The presence of NH groups on the ligands assists the insertion and can provide an interesting isomerization of these coordinated fragments (Figure 48) [187,188]. Stable low-coordinate organometallic complexes, using bulky guanidinato ligands, allow agostic interactions between the yttrium atom and the tert-butyl group in the solid state for [{(Me 3 Si) 2 NC(NCy) 2 } 2 YtBu] 76 [183] or with two methyl carbon atoms of SiMe 3 groups in [{(Me 3 Si) 2 NC(NCy) 2 } 2 Y(µ-CH 2 SiMe 3 ) 2 Li] 77 [184].…”

“…The presence of NH groups on the ligands assists the insertion and can provide an interesting isomerization of these coordinated fragments (Figure 48) [187,188]. In contrast to the usual lack of reactivity observed in guanidinates of other metals, certain organolanthanides allow examples of the insertion of small unsaturated molecules into the metal-guanidinate bond.…”

For decades, ligands such as phosphanes or cyclopentadienyl ring derivatives have dominated Coordination and Organometallic Chemistry. At the same time, alternative compounds have emerged that could compete either for a more practical and accessible synthesis or for greater control of steric and electronic properties. Guanidines, nitrogen-rich compounds, appear as one such potential alternatives as ligands or proligands. In addition to occurring in a plethora of natural compounds, and thus in compounds of pharmacological use, guanidines allow a wide variety of coordination modes to different metal centers along the periodic table, with their monoanionic chelate derivatives being the most common. In this review, we focused on the organometallic chemistry of guanidinato compounds, discussing selected examples of coordination modes, reactivity and uses in catalysis or materials science. We believe that these amazing ligands offer a new promise in Organometallic Chemistry.
