A mechanistic investigation of the Pd-catalyzed cross-coupling betweenN-tosylhydrazones and aryl halides

“…Nitrogen, like ethylene, also has a molecular weight of 28 Da, and is present in abundance during the ESI-MS experiment thanks to its use as a desolvation gas, and was a possible explanation for this ion. While many dinitrogen complexes have been reported for metal centers in Groups 3-9, some simple, [267][268][269][270][271] some with carefully constructed coordination environments, [272][273][274][275][276][277][278][279][280] and others evolved for nitrogen fixation, [281][282][283][284][285] such complexes are less common in Groups 10 and 11. Isolated dinitrogen complexes involving platinum are unknown.…”

Lewis Structures and the Bonding Classification of End-on Bridging Dinitrogen Transition Metal Complexes

“…Although it has historically been difficult to predict which mode will be adopted, we recently showed that an MO-based analysis considering the number of delectrons supplied by the two metals to the p-MNNM manifold can correctly predict the preference for end-on terminal or bridged coordination (eq 1). 14 (eq 1) Side-on bridging N2 coordination is also known, with the nature of the metal and steric factors proposed to be responsible for controlling which bridging mode is adopted; [15][16][17][18][19] however, we focus on end-on binding here.…”
