1. INTRODUCTION The chemistry of three-membered ring heterocycles has played a
dominant role in the history of organic synthesis. 1 Countless classic and modern protocols …

Non-heme iron enzymes promote a number of important biological reactions, including
serotonin, 1 leukotreine, 2 and DNA3 synthesis. Most mononuclear non-heme iron enzymes …

In a series of notable manuscripts in the early 1960s, Daryle H. Busch and co-workers
described reactions of coordinated ligands, particularly choosing mercaptoamines (NS) to …

The diamino-dithiolato N2S2 ligand N, N '-bis-2-methyl-mercaptopropyl-N, N '-
dimethylethylenediamine, H2 (bmmp-dmed), and its nickel (1) and zinc (2) complexes have …

The S-oxygenation of cysteine with dioxygen to give cysteine sulfinic acid occurs at the non-
heme iron active site of cysteine dioxygenase. Similar S-oxygenation events occur in other …

A series of iron (III) chloride and iron (III) μ-oxo compounds supported by tetradentate amino-
bis (phenolate) ligands containing a homopiperazinyl backbone were prepared and …

Cysteinate oxygenation is intimately tied to the function of both cysteine dioxygenases
(CDOs) and nitrile hydratases (NHases), and yet the mechanisms by which sulfurs are …

The reactivity between a thiolate-ligated five-coordinate complex [FeII (SMe2N4 (tren))]+(1)
and dioxygen is examined in order to determine if O2 activation, resembling that of the …

Syntheses and characterization of [(cyclamacetate) FeF] PF6 (1) and the corresponding N-
methylated complex [(trimethylcyclamacetate) FeF] PF6 (3) are presented. Compound 1 is …

A series of tetragonally distorted square pyramids of formula N2S2M (NO)(M= Fe, Co) is
prepared and characterized by ν (NO) IR and EPR spectroscopies, magnetism and …
