Metal-free chalcogenation of cycloketone oxime esters with dichalcogenides

We report the metal-free chalcogenation of cycloketone oxime esters with dichalcogenides via a radical process. Because of the metal-free condition and use of readily accessible dichalcogenides, this method is an effective and green strategy for the synthesis of chalcogen-substituted butyronitrile.

Conjugate addition of thiols to p-benzoquinone monoketals. Attempts to prepare chiral synthetic equivalents of p-benzoquinone

The conjugate addition of several thiols to achiral and chiral p-benzoquinone monoketals has been studied. A chiral synthetic equivalent of p-benzoquinone has been obtained in both enantiopure forms. Springer-Verlag lberica 1997.

B12 Mimicry in a Weak Ligand Environment: Oxidation and Alkylation of Thiols

The first examples of alkylation and oxidation of thiols by cobalt in weakly coordinating ligand (MeCN) environments is presented as a mimic to B12-dependent nonenzymatic reaction.

RADIKALIONEN 89. EINELEKTRONEN-OXIDATIONEN VON DIARYLDISULFIDEN MIT AlCl3/H2CCl2

The single electron oxidation of 14 alkyl and alkoxy substituted diaryldisulfides by AlCl3/H2CCl2 has been investigated by ESR/ENDOR spectroscopy.The radical cations observed prove the following skeletal rearrangements: Those with ring hydrogens in ortho positions to the disulfide bridge preferentially form thianthrene derivatives.The isomeric dinaphthyl disulfides react differently, the 2,2'-isomer yielding the dibenzothianthrene radical cation and the 1,1'-isomer the well-known naphthalene-1,8-disulfide radical cation.For all diaryl disulfides with completely alkyl- or methoxy-blocked ortho positions, oxidative desulfuration is observed.As substantiated by additional (2)D and (33)S isotope marking, the bis(2,5-dimethoxyphenyl)disulfide reacts both to the corresponding thianthrene derivative as well as via desulfuration to the radical cation of the monosulfide.Accompanying cyclovoltammetric and photoelectron spectroscopic measurements prove that all ESR spectroscopically detected radical cations result from compounds Ar-S-Ar, Ar-SS-Ar and Ar(S)2Ar with rather low oxidation or ionisation potentials and thus suggest that each the most easily oxidized paramagnetic species is observed in the rather complex product mixtures, which form on AlCl3/H2CCl2 oxidation of diaryldisulfides. Key words: Diaryl disulfides; one-electron oxidation; radical cations; ESR/ENDOR spectra.

A MILD REDUCTION OF ARENESULFONIC ACID AND ITS DERIVATIVES WITH DIPHOSPHOROUS TETRAIODIDE

When treated with diphosphorous tetraiodide in boiling acetonitrile or under neat conditions, arenesulfonic acids, their salts, chlorides, esters, and amides are reduced to aryl disulfides in good to moderate yields.
