Reactivity of sulfur nucleophiles towards S-nitrosothiols

Munro, Andrew P., Williams, D. Lyn H.·2000·Journal of the Chemical Society Perkin Transactions 2

Abstract

Rate constants have been measured for the reactions of a range of S-nitrosothiols with the following sulfur-centred nucleophiles: sulfite ion, thiourea, thiocyanate ion, thiosulfate ion, thiomethoxide ion and sulfide ion. Many of the reactions were very fast and were followed in a stopped-flow spectrophotometer. For the sulfite reaction the reactive species over the pH range 4–8 was shown to be exclusively SO32−. For two RSNO species the reactivity sequence was established as: SO32− > MeS− > S2O32− ≫ SC(NH2)2 > SCN−. The reaction with sulfide ion was also rapid and generated a fairly stable yellow species (λmax 410 nm), which was probably the nitrosodisulfide ion ONSS−, but the absorbance–time data were too complex for a simple kinetic analysis. This reaction could have some potential as an analytical procedure for the determination of RSNO species. The kinetic results are discussed in terms of the factors affecting nucleophilicity and are compared with the corresponding reactions of other nitrosating species.

  • Taken together, nitrite reacts with S8 and, seemingly less efficiently, with polysulfides in non-aqueous polar solvents to form products including SSNO-.

    “Taken together, nitrite reacts with S8 and, seemingly less efficiently, with polysulfides in non-aqueous polar solvents leading to the formation of similar products as observed previously in the reaction of NO with sulfide [69], and nitrosothiols with thiols [70], and with sulfide [19,71] including SSNO -.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
