On the Reactions of Thiols, Sulfenic Acids, and Sulfinic Acids with Hydrogen Peroxide

The reaction of thiols with H2O2 is central to many processes essential to life, from protein folding to redox signaling. The initial products are assumed to be sulfenic acids, but their observation, and the kinetic and mechanistic characterization of their subsequent reactions, has proven challenging. The introduction of a 9-fluorotriptycene substituent enabled the use of 19F NMR to directly monitor the reaction of a thiol with H2O2 to yield a sulfenic acid, and its subsequent oxidation to sulfinic and sulfonic acids. The oxidations are specific base catalyzed, as revealed by the lack of isotope effects and the dependence of the kinetics on pH but not buffer concentration.
Fluorination of Bi- and polycyclic aromatic hydrocarbons with N-fluorobis(phenylsulfonyl)amine in the absence of solvent

experimental part, p. 1317 - 1322 (2011/01/04)
Reactions of N-fluorobis(phenylsulfonyl)amine with naphthalene, 1-methylnaphthalene, phenanthrene, anthracene, and pyrene without solvent were investigated. Sometimes the fluorination of aromatic compounds with N-fluorobis(phenylsulfonyl)amine without solvent proceeded more selectively than at the use of fluorinating reagents in solution.

The synthetic utility of N-fluoro-2,4-dinitro-imidazole NF-2,4-DNT, a recently introduced NF fluorinating agent, has been tested for direct one-pot fluorination of several classes of polycyclic aromatic hydrocarbons, PAHs, namely pyrene, crowded alkyl(cycloalkyl)-pyrenes; hexahydro-and tetrahydro-pyrene; benzo[a]anthracene; benzo[a]-and benzo[e] pyrene; perylene; 2,7-di-tert-butylphenanthrene;chrysene; 9-imethylanthracene and anthracene, as well as trans-15:16-dimethyl-dihydropyrene: azulene[2-a]lacenaphthylene and azulene. Although the isolated yields are modest, the ease of handling of the reagent, simple operation (reflux in dichloroethane for 3 days) and the use of 1.1 equivalent of the reagent makes the procedure quite attractive for polynuclear aromatics, avoiding multi-step operations (NO2-PAH → NH2-PAH → N2+-PAH → F-PAH) or the use of toxic or costly reagents (CF3OF, XeF2, etc.); it provides direct one-pot access to a variety of F-PAHs that are not readily made using: other fluorinating agents.
