Oxidations of hemoglobin in oxygen-saturated and deoxygenated media by 10 structurally variant alkyl nitrites have been examined in kinetic detail. Pronounced structural influences on rate constants, whose values span a ...

The reactions of human hemoglobin with sodium nitrite and ethyl nitrite in deoxygenated media have been examined in kinetic detail. Nitrous acid has been identified from kinetic pH dependence studies as the principal oxidant ...

The reactions of human hemoglobin and sperm whale myoglobin with ethyl nitrite under aerobic conditions have been examined in kinetic detail. Ethyl nitrite converts two equivalents of oxyhemoglobin or oxymyoglobin to their ...

In anaerobic phosphate buffer, pH 6.3-7.5, deoxyhemerythrin is oxidized to semi-methemerythrin (semi-met) by excess sodium nitrite. This oxidation is quantitative as judged by EPR spectroscopy. Further oxidation to ...

A plausible explanation for the unprecedented formation of two conformational isomers of bisphenyldirhodium(III) caprolactamate is presented. The presence of acetic acid during the coupling process leading to the formation ...

Asymmetric catalysis of metal carbene transformations with unique chiral dirhodium(II) carboxamidates provides highly enantioselective, diastereoselective, and regioselective syntheses of lactones and lactams via ...

Dirhodium(ll) tetraacetate in combination with catecholborane catalyzes the isomerization of alkenes and dienes. Effective isomerization occurs at 80-135°C with the use of only 0.1 mol % rhodium acetate. With 2-methyl-1, ...

A substituted donor–acceptor cyclobutenecarboxamide is synthesized with modest enan tiocontrol through a chiral copper(I) complex catalyzed [3 + 1]-cycloaddition reaction of α-acyl diphenylsulfur ylides with 3-siloxy-2-d ...

Enoldiazo esters and amides have proven to be versatile reagents for cycloaddition reactions that allow highly efficient construction of various carbocycles and heterocycles. Their versatility is exemplified by (1) ...
