“…However, the amide pK a strongly varies with metal, charge, and coligands. [19] The strongly reduced N 2 -ligand and/or metal ions of 2 possibly offer alternative kinetic protonation sites. For example, protonation of an N 2 -derived Mo IV pincer nitride gave a Mo/P-bridging hydride, [6d] while amide ligand protonation was observed for a triamidoamine Mo À N 2 complex.…”

“…Compared to the ethylene-bridged PNP amido ligand, the (L 4 ) À pincer is characterized by higher conformational rigidity but electronic flexibility: While the radical complexes from the oxidation of iridium(I) dialkylamides are generally transient species, the metalloradical 1 and the oxidation product 2 are sufficiently stable to be easily isolated. [7,25] Thus the new dieneamido ligand opens up the opportunity to examine an unusual one-electron reactivity of iridium.…”

“…[11] Während diese durch Oxidation des L 1 -zum L 4 -Liganden abgeschwächt werden sollte, ist zu erwarten, dass die kationische Ladung und der Wechsel zum 5d-Metall die M-N-Bindung stärken. [24] Zusammenfassend gelingt durch einfache oxidative Ligandmodifikation des PNP-Chelatliganden die Isolierung quadratisch-planarer d 7 [7,25] Somit erçffnet der …”
