“…Ruthenium nitrosyl complexes were first reported by Joliet, who prepared and isolated RuCl 3 (NO) and related compounds, especially [Ru(NH 3 ) 4 (OH)(NO)]Cl 2 , and reported these findings in 1889. , The iconic tetra- and pentammine nitrosyl compounds were subsequently investigated in much detail, starting with a report by Werner in 1907, and followed with work by Gleu and Büddecker, Taube, Bottomley, and others . The crystal structure of [Ru(NH 3 ) 5 (NO)]Cl 3 was reported first in an original publication in Russian by Khodashova in 1965, and later re-investigated by Bottomley (because of the observed disorder) .…”

Nitric oxide (NO) is an important signaling molecule that is involved in a wide range of physiological and pathological events in biology. Metal coordination chemistry, especially with iron, is at the heart of many biological transformations involving NO. A series of heme proteins, nitric oxide synthases (NOS), soluble guanylate cyclase (sGC), and nitrophorins, are responsible for the biosynthesis, sensing, and transport of NO. Alternatively, NO can be generated from nitrite by heme- and copper-containing nitrite reductases (NIRs). The NO-bearing small molecules such as nitrosothiols and dinitrosyl iron complexes (DNICs) can serve as an alternative vehicle for NO storage and transport. Once NO is formed, the rich reaction chemistry of NO leads to a wide variety of biological activities including reduction of NO by heme or non-heme iron-containing NO reductases and protein post-translational modifications by DNICs. Much of our understanding of the reactivity of metal sites in biology with NO and the mechanisms of these transformations has come from the elucidation of the geometric and electronic structures and chemical reactivity of synthetic model systems, in synergy with biochemical and biophysical studies on the relevant proteins themselves. This review focuses on recent advancements from studies on proteins and model complexes that not only have improved our understanding of the biological roles of NO but also have provided foundations for biomedical research and for bio-inspired catalyst design in energy science.

“…These results are consonant with the formation of 7a and 10a, with the eventual destruction of 10a and its successor 11a by attack on the solvent. As substantiation for the existence of such a boracyclopropene nucleus as a diphenyl(diphenylvinylene)borate(III) salt (7), we were then able to observe a highly selective 1,2-phenyl shift in the irradiation of lithium triphenyl(phenylethynyl)borate(III)5 (9) in THF, where acetolysis of the reaction products gave a 1:5.6 ratio of biphenyl to stilbene. The formation of the latter was stereospecific, however, as only the cis isomer was detected.…”

“…The biphenyl obtained in 40-70% overall yield by the irradiation in THF solution of either sodium tetraphenylborate(IIl) (1) or in 15% yield from lithium triphenyl(phenylethynyl)borate(III) (9), followed by treatment with DOAc, was ca. 65% undeuterated and 35% monodeuterated.…”

“…attack at the nitrosyl ligand has been demonstrated for a variety of ruthenium complexes. [1][2][3][4][5][6][7][8][9] Particularly noteworthy are the reactions of [RunCl(das)2NO]2+ (das = o-phenylenebisdimethylarsine) with hydrazine, forming [RuIIClN3(das)2],1 and with azide ion, forming [RunClN3(das)2], N20, and N2.2 A similar reaction was also found for [RunCl-(dipy)2NO]2+ (dipy = 2,2'-dipyridine).3 We have investigated reactions of nitrosylpentaammineruthenium(II), [Run(NH3)sNO]3+,4-6 and present here the results of investigations of reactions of [Run(NH3)5-NO]3+ with hydroxylamine and hydrazine which give (dinitrogen oxide)pentaammineruthenium(II), [Ru11-(NH3)5N20]2+. N20 complexes of pentaammineruthenium(II) were prepared previously from N20 and [Run(NH3)6H20]2+.10-12…”
