Abstract

Endlich, die terminalen Mangan(v)‐Imidokomplexe, die postulierten Zwischenprodukte von Aminierungs‐ und Aziridinierungsreaktionen, wurden hergestellt. Die Synthese der strukturell gut charakterisierten (Imido)mangan(v)‐Corrole 2 und 3, die mit elektronenreichen Nucleophilen wie organischen Phosphanen reagieren, beruht auf der Reaktion von Mangan(III)‐Corrolen mit organischen Aziden unter Photolysebedingungen.

Mid- to high-valent imido and nitrido complexes of iron

“…Though terminal imido complexes of ruthenium and osmium have been known for many years, terminally bonded iron imido complexes remain relatively scarce [24,25]. The first structural characterization of a terminal iron-imide linkage came from the Lee group [34].…”

“…Although mid-to high-valent iron complexes containing multiple bonds to nitrogen atoms remain relatively uncommon, a small body of literature has emerged in recent years parallelling the related literature that describes iron-oxo species. The transition metal chemistry of imides and nitrides was reviewed as recently as 2003, [24][25][26][27][28] but it seemed to us prudent to provide a short and focused survey of some of the most recent literature on the preparation and properties of mid-to high-valent iron imides and nitrides. In this review, we focus on both terminal and bridging imide and nitride species, and discuss the electronic factors thought to stabilize these species.…”

Synthesis and Properties of FeIII N=MnIV Heterometallic Complex with Tetra-tert-butylphthalocyanine Ligands

“…Nitrido complexes of manganese(V) are generally synthesized by the oxidation of Mn III derivatives by chlorine or sodium hypochlorite in the presence of ammonia or by photolysis of corresponding Mn III azido complexes. [19,20] In the current study the complex 3 could in fact be prepared by reacting the appropriate acetatomanganese(III) complex with an excess of sodium azide in high-boiling solvents, like xylene or α-chloronaphthalene. This approach allows significantly milder and more practical reaction conditions than those traditionally employed (no strong oxidants or UV light).…”

Strong π-interactions between tantalum and apical ligands in square pyramidal complexes supported by a rigid tetradentate spectator ligand

“…For instance, metal oxo complexes have been extensively used in epoxidation of alkenes [2], atom-transfer reactions to compounds containing C=O, C=N, C=C and C≡C bonds [3,4], C-H bond activation [5], and other important transformations [6,7]. The analogous metal imido complexes have been used in related reactions, including aziridination of alkenes [8,9], selective reduction of compounds containing C=X multiple bonds [4], C-H activation of hydrocarbons [10], and more [6,11,12]. Transition metal nitrido complexes have been used in a wide range of stoichiometric and catalytic reactions [6,11,13].…”

Transition metal nitrido complexes have been used in a wide range of stoichiometric and catalytic reactions [6,11,13]. Furthermore, both metal imido and nitrido complexes are key intermediates in the reduction of dinitrogen to form ammonia [14][15][16][17].…”
