摘要:

The synthesis and reactions of four groups of conjugated sulfur-containing compounds; i.e. 1-nitro-2(4)-thioethenes (and -dienes) and 1-nitro-2(4)-sulfonylethenes (and -dienes), which have become known in recent years, are discussed. Nitrothioethenes may be obtained by elimination reactions of nitrothioketals (synthesised from α-nitro ketones) and nitrohalothioethanes (synthesized from α-nitro-β-acetoxyethanes), as well as by halogen or nitro group displacement by a thio group in 1-nitro-2-halo- or 1,2-dinitroethenes. The last method was used for nitrothiodiene preparation from dinitrodienes. The stereochemistry of the thiylation of conjugated dinitro compounds is described. Nitrosulfonylethenes and -dienes can be obtained by oxidation of the corresponding nitro sulfides as well as by nitrovinylation of arenesulfinates with dinitroethenes and -dienes. Two-electron oxidation of 1-nitro-2-sulfonylethane dianions is suitable for the preparation of 1-nitro-2-sulfonylethenes. Nucleophilic displacement of the sulfur-containing group in nitrothio(sulfonyl)ethenes by amines, alkoxide and thiolate ions as well as Diels-Alder reactions are described. The spectral data (1H NMR, IR, UV) of the compounds mentioned are discussed.

摘要:

In the present review the results of investigations of the chemical properties of polyhalovinyl sulfones are summarized. The main accent is made on their ability to react with nucleophiles at different electrophilic sites depending on the nature and the number of halogen substituents as well as on the nucleophile. Special attention is given to the halophilic reduction of these electrophiles by soft nucleophiles. The synthetic potential of polyhalovinyl sulfones as synthons for various heterocycles in reactions with polydentate S- and N-nucleophiles is also demonstrated.

摘要:

Marvin Carmack was born in 1913 near Dana, Vermillion County, Indiana, U.S.A., and attended public schools there. He graduated from the University of Illinois in 1937 with A.B. Honors in Chemistry. During 1937–40 he earned the M.S. and Ph.D. degrees at the University of Michigan, working with Professor Werner E. Bachmann on the synthesis of substituted benzopyrene compounds as potential carcinogens. At Michigan he carried out his first experiments with the Willgerodt Reaction, which remained one continuing subject of his interest for the next fifty years-an interest that broadened to include many aspects of sulfur chemistry.

摘要:

1,2-Dithiete and its derivatives have received much attention because of their unique bonding properties, although only a few have been isolated so far. This paper reviews the literature concerning 1,2-dithietes, 1,2-diselenetes, and 1,2-thiaselenetes.
