SULFUR-CONTAINING CARBOXYLIC ACIDS. 5. SYNTHESIS AND STRUCTURE OF DIALKYL SULFIDES AND DIALKYL SULFOXIDES WITH VICINAL CARBOXYL OR ACYLAMINO GROUPS

Bifunctional sulfides and sulfoxides containing carboxy, carbamoyl, or acylamino groups in the β-position are synthesized, and their IR spectra were studied.An unusual decrease in the frequencies of the carbonyl vibrations (by 20-34 cm-1) was found for thiodipropionic acid, its amides, and bis(β-acylaminoethyl) sulfides by comparison with the corresponding sulfoxides.The low-frequency shift of the CO bond in these carbonylsulfides was not, as expected, associated with the intramolecular S...O coordination, since the x-ray structural investigation of thiodipropionic acid and bis(2-trifluoroacetylaminoethyl) sulfide did not show short intra- and intermolecular contacts involving the sulfur atom.Both structures contain intermolecular hydrogen bonds (C=O...HO or C=O...HN).Keywords: derivatives of thiodipropionic acid, 2-(acylaminoethyl) sulfides, derivatives of β,β'-sulfinyldipropionic acid, 2-(acylaminoethyl) sulfoxides, x-ray structural analysis, bis(2-trifluoroacetylaminoethyl) sulfide, molecular structure.

An efficient and straightforward access to sulfur substituted [2.2]paracyclophanes: Application to stereoselective sulfenate salt alkylation

A straightforward and high-yielding access to various [2.2]paracyclophanes possessing a sulfur-based functional group is reported, the key step being a SEAr reaction mediated by a sulfonium salt. The versatility of the methodology was exemplified by an original application in sulfenate salt chemistry, from which a remarkable chirality transfer was observed.

Antioxidative properties of phenyl-substituted phenols. Part I. The mechanism of synergism between 4-alkoxy-2,6-diphenylphenols and ββ′-disubstituted diethyl sulphides

A pronounced synergism between 4-alkoxy-2,6-diphenylphenols and ββ′-disubstituted diethyl sulphides has been observed in the inhibition of autoxidation of polypropene at 180°C. The mechanism of this synergistic action (at temperatures ≥150°C) has been investigated. N.m.r. model experiments have shown that the phenolic antioxidant (AH) is regenerated continuously from the phenoxyl radical (A·) by hydrogen atom donation by the sulphenic acid, a product originating from the ββ′- disubstituted diethyl sulphide. This observation is of possible contributory importance to the understanding of the mechanism of synergistic effects.
