C-H amination and amidation by catalytic nitrene transfer are well-established typically proceed via electrophilic attack of nitrenoid intermediates. In contrast, the insertion (formal) terminal nitride ligands into bonds is much less developed nitrogen atom remains unknown. We here report synthesis a formal complex palladium. Photocrystallographic, magnetic, computational characterization support assignment as an authentic metallonitrene (Pd-N) with diradical ligand that singly bonded to Pd
Transition-metal nitrides/nitrenes are highly promising reagents for catalytic nitrogen-atom-transfer reactivity. They typically prepared in situ upon optically induced N2 elimination from azido precursors. A full exploitation of their potential, however, requires in-depth knowledge the primary photo-induced processes and structural/electronic factors mediating loss with birth terminal metal-nitrogen core. Using femtosecond infrared spectroscopy, we elucidate here molecular-level mechanisms...

Abstract Übergangsmetallnitride/nitrene sind vielversprechende Reagenzien für katalytischen Stickstoffatomtransfer, die in situ durch optisch induzierte N 2 ‐Eliminierung aus Azidkomplexen zugänglich sind. Um ihr synthetisches Potenzial Katalyse voll ausschöpfen zu können, ist ein grundlegendes Verständnis der primären photoinduzierten Prozesse und stereoelektronischen Faktoren, welche ‐Dissoziation kontrollieren, unerlässlich. Mit Hilfe von Femtosekunden‐Infrarotspektroskopie klären wir...
Reaction of TaMe3Cl2 with the rigid acridane-derived trisamine H3NNN (1) yields tantalum(V) complex [TaCl2(NNNcat)] (2). Subsequent reaction dioxygen results in full four-electron reduction O2 yielding oxo-bridged bimetallic [{TaCl2(NNNsq)}2O] (5). This dinuclear exhibits an open-shell ground state due to partial ligand oxidation and was comprehensively characterized by single crystal X-ray diffraction, LIFDI mass spectrometry, NMR, EPR, IR UV/VIS/NIR spectroscopy. The mechanism activation...
