“…8b In some systems, electrochemical oxidation of ammine complexes yields metalnitride products. 41,42,44 Other systems can generate N 2 as a product from the oxidation of NH 3 -derived ammine complexes, either through chemical 36,40,[47][48][49] or electrochemical [49][50][51][52] methods. These include recently reported homogeneous systems that catalytically form N 2 from NH 3 through both chemical [43][44][45] or electrochemical 44,[53][54][55] N-H bond oxidation.…”

Oxidation of the nucleophilic nitride, (salen)Mn≡N (1) with stoichiometric [Ar N][X] initiated a nitride coupling reaction to N , a major step toward catalytic ammonia oxidation (salen=N,N'-bis(salicylidene)-ethylenediamine dianion; Ar=p-bromophenyl; X=[SbCl ] or [B(C F ) ] ). N production was confirmed by mass spectral analysis of the isotopomer, 1- N, and the gas quantified. The metal products of oxidation were the reduced Mn dimers, [(salen)MnCl] (2) or [(salen)Mn(OEt )] [B(C F ) ] (3) for X=[SbCl ] or [B(C F ) ] , respectively. The mechanism of nitride coupling was probed to distinguish a nitridyl from a nucleophilic/electrophilic coupling sequence. During these studies, a rare mixed-valent Mn /Mn bridging nitride, [(salen)Mn (μ-N)Mn (salen)][B(C F ) ] (4), was isolated, and its oxidation-state assignment was confirmed by X-ray diffraction (XRD) studies, perpendicular and parallel-mode EPR and UV/Vis/NIR spectroscopies, as well as superconducting quantum interference device (SQUID) magnetometry. We found that 4 could subsequently be oxidized to 3. Furthermore, in view of generating a catalytic system, 2 can be re-oxidized to 1 in the presence of NH and NaOCl closing a pseudo-catalytic "synthetic" cycle. Together, the reduction of 1→2 followed by oxidation of 2→1 yield a genuine synthetic cycle for NH oxidation, paving the way to the development of a fully catalytic system by using abundant metal catalysis.
