	abstract = {Selective alpha-C-H activation results in the synthesis of the first bridging metallaaziridine complex for the catalytic alpha-alkylation of primary amines. Reaction development led to the preparation of new Zr 2-pyridonate complexes for this useful transformation. No nitrogen protecting groups are required for this reaction, which is capable of assembling quaternary chiral centers a to nitrogen. Preliminary mechanistic investigations suggest bridging metallaaziridine species are the catalytically active intermediates for this alpha-functionalization reaction, while monomeric imido complexes furnish azepane hydroamination products.},

	abstract = {The wood rotting fungus, Phaeolus schweinitzii, efficiently transforms the antimony(III) compounds potassium antimony tartrate and antimony trioxide to nonvolatile dimethylantimony and trimethylantimony species, The organoantimony species were detected in potato dextrose broth media samples by using hydride generation-gas chromatography-atomic absorption spectroscopy (HG-GC-AAS). The average concentrations of trimethylantimony species after 40 days incubation with potassium antimony tartrate were approximately 35 mug, 155 mug and 520 mug Sb/l, for substrate concentrations of 10 mg, 100 mg and 1000 mg Sb/l respectively. Thus, the maximum yield of trimethylantimony species was approximately 0.4\%, When antimony trioxide (saturated solution, 4 mg Sb/l) was used as a substrate, the average concentration of trimethylantimony species was 150 mug Sb/l after 40 days. The HG-GC-AAS response for the dimethylantimony species was less than that for the trimethylantimony species; however, quantification was not possible because of the lack of an appropriate standard. In comparison, cultures of P, schweinitzii incubated with 1 mg As/I as sodium arsenite contained approximately 200 mug As/I as trimethylarsenic species, i.e. 20\% yield, Biomethylation of antimony(V) was inefficient: cultures contained only 3 mug Sb/l as trimethylantimony species after incubation with 100 mg Sb/l as potassium hexahydroxyantimonate, No organoantimony species were detected in control cultures that contained only medium and inorganic antimony compounds. The identities of the organoantimony species were confirmed by using CC-Mass Spectrometry, Copyright (C) 2001 John Wiley \& Sons, Ltd.},

DMPO-C110 was detected exclusively over a range of DMPO concentrations (DMPO:protein ratios 25-100 mol/mol). Treatment of human Mb (or Y103F Mb) with the ONOO- generator 5-amino-3-(4-morpholinyl)-1,2,3-oxadiazolium (SIN-1) chloride (ONOO-: protein 5 mol/mol) yielded a cross-linked Mb dimer as judged by SDS-PAGE analyses. Addition of DMPO or carbonate effectively eliminated the cross-linked product. Mass analyses of samples containing human Mb (or Y103F Mb), carbonate, and ONOO- indicated that nitration occurs exclusively at Y103. Thus, reaction of human Mb and ONOO- yields specific products that depend on the presence or absence of physiological concentrations of carbonate. These products may serve as biomarkers for the participation of Mb-derived radicals in the oxidative damage associated with myocardial reperfusion injury. (C) 2001 Academic Press.},

	abstract = {The filamentous fungus Scopulauiopsis brevicaulis biomethylates inorganic antimony(III) compounds to trimethylstibine, that can be detected in culture headspace gases. Dimethylantimony and trimethylantimony species have been detected in the medium of these cultures, but the origin of these species was controversial. We now show that the dimethylantimony species is a true intermediate on the pathway to trimethylstibine (rather than arising from trimethylstibine oxidation or as an analytical artifact) because no dimethylantimony species are formed on trimethylstibine oxidation, as determined by using HG-GC-AAS. Furthermore, the dimethylantimony and trimethylantimony species can be separated, by using anion exchange chromatography, and so the dimethylantimony species is not an analytical artifact, formed during the hydride generation process. The antimony biomethylation mechanism was further probed by measuring incorporation of the methyl group, from (CD3)-C-13-L-methionine and CD3-D-methionine, into methylantimony species and, for comparison, into methylarsenic species. The percentage incorporation of the labeled methyl group into methylarsenic and methylantimony species was not significantly different. The incorporation from (CD3)-C-13-L-methionine was 54\% and 47\% for antimony and arsenic, respectively. The incorporation from CD3-D-methionine was 20\% and 16\% for antimony and arsenic, respectively. It appears that the biomethylation of arsenic and antimony occur by very similar, perhaps identical, mechanisms. (C) 2000 Elsevier Science Ltd. All rights reserved.},

	abstract = {Cultures of the fungus Scopulariopsis brevicaulis were grown in antimony-rich media. Although volatile compounds of other elements were readily detected in the culture headspace, volatile antimony compounds were formed irreproducibly and at only ultratrace levels. In order to monitor the media for nonvolatile methylantimony compounds, a method of sample preparation was developed, based on solid-phase extraction. This enabled the separation of large quantities of soluble inorganic antimony species from trace amounts of organo-antimony compounds before speciation by HG-GC-AAS, By this methodology methylated antimony compounds were detected at concentrations of 0.8- 7.1 mu g Sbl(-1) in all media in which S. brevicaulis was grown in the presence of antimony(III) compounds. These methylantimony species were not detected in any of the nonliving or medium-only controls. Methylated compounds were not detected where S. brevicaulis was grown in the presence of antimony(V) compounds. This is the first study to show that antimony(III) compounds are biomethylated by S. brevicaulis under aerobic-only growth conditions. (C) 1998 John Wiley \& Sons, Ltd.},

At high nitrile concentrations, the principal species present is RuCl(PP)(RCN)(3)X-+(-) (X = Cl); the cation can generally be isolated (as the PF6 salt) by abstraction of the chloride counterion with NH4PF6. Use of 2 equiv of NH4PF6 generates Ru(PP)(RCN)(4)(2+)(PF6-)(2) (PP = dppb). In the absence of a halide-abstracting agent, addition of hexanes or diethyl ether precipitates neutral RuCl2(PP)(RCN)(2) species, which undergo further loss of nitrile in the solid state (R = Me) or in solution (R = Me, Ph). Redissolution of the neutral species in chlorocarbon solvents gives Ru2Cl3(PP)(2)(RCN)(2)X-+(-) (X = Cl) and, in benzene, Ru2Cl4(PP)(2)(RCN). The dinuclear cation (X = PF6) is also accessible by reaction of RuCl(PP)(RCN)(3)+PF6- with CH2Cl2 or CDCl3, while the mononitrile can be obtained directly by reaction of Ru2Cl4(PP)(2) or RuCl2(PP)(PPh3) with small amounts of nitrile in benzene.},
