PhB(OH)2-Promoted Electrochemical Sulfuration-Formyloxylation of Styrenes and Selectfluor-Mediated Oxidation-Olefination

We report a PhB(OH)2-promoted electrochemical sulfuration-formyloxylation reaction of styrenes employing commercially available thiophenols/thiols as thiolating agents. Specifically, metal catalysts and external chemical oxidants are not needed in the reaction for the formation of β-formyloxy sulfides, and these sulfides can be further converted to (E)-vinyl sulfones via the Selectfluor-mediated oxidation-olefination. Notably, on the basis of this electrochemical oxidation strategy, β-hydroxy sulfide, β-formyloxy sulfoxide, β-formyloxy sulfone, and (E)-vinyl sulfoxide can also be easily prepared.

Vinyl sulfone synthesisviacopper-catalyzed three-component decarboxylative addition

The synthesis of vinyl sulfone derivativesviathe reaction of arylpropiolic acids, K2S2O5, and aryl boronic acids is reported. The CuBr2/1,10-phenanthroline catalytic system in the presence of acetic acid provide

Base-controlled divergent synthesis of vinyl sulfones from (benzylsulfonyl)benzenes and paraformaldehyde

A tuneable metal-free protocol for the selective preparation of a-substituted vinyl sulfone and (E)-vinyl sulfone derivatives has been described. In this process, stable paraformaldehyde was used as the carbon source. The base played an important role in the selectivity control of transformations. More than 50 products were synthesized with excellent chemoselectivity and broad functional group tolerance.

Electrochemical Synthesis of Vinyl Sulfones by Sulfonylation of Styrenes with a Catalytic Amount of Potassium Iodide

An electrochemical sulfonylation reaction of styrenes was developed in which sodium arylsulfinates were used as sulfonylating reagents, a catalytic amount of KI was used as a redox mediator, and Bu 4NBF 4was used as the electrolyte. In addition to various styrenes, sodium arylsulfinates with either electron-donating or electron-withdrawing groups were tolerated.

Cu-catalyzed dehydrogenative olefinsulfonation of Alkyl arenes

A copper-catalyzed reaction protocol for the dehydrogenation of ethylbenzenes into styrene derivatives has been developed. This reaction procedure proceeded well under mild reaction conditions, providing a practical and efficient strategy for the rapid assembly of biologically and pharmaceutically significant molecules, such as vinyl sulfone. Simple alkyl arenes were functionalized via consecutive β-elimination in the presence of N-sulfonylbenzo[d]imidazole with broad substrate scope and good functional group tolerance.

Photocatalyst-free visible light driven synthesis of (E)-vinyl sulfones from cinnamic acids and arylazo sulfones

A photocatalyst-free visible light mediated decarboxylative sulfono functionalization protocol has been explored for the synthesis of (E)-vinyl sulfones from cinnamic acids and bench-stable arylazo sulfones. The latter have been utilized as sulfonyl radic

N,N′-Disulfonylhydrazines: New sulfonylating reagents for highly efficient synthesis of (E)-vinyl sulfones at room temperature

N,N′-Disulfonylhydrazines have been proven to be the most reactive precursors of sulfonyl radicals in all types of sulfonyl substituted hydrazines as early as a half century ago. But such function has not been applied in organic synthesis except the formation of disulfones by self-dimerization of sulfonyl radicals. In this article, they were introduced as new sulfonylating reagents and their combinations with NIS and Et3N were established as excellent iodosulfonylating reagents for alkenes. Finally, a highly efficient method for the synthesis of (E)-vinyl sulfones was developed by mixing an alkene, a N,N′-disulfonylhydrazine, NIS and Et3N in THF at room temperature for 5 min.

Electrochemical sulfonylation of alkenes with sulfonyl hydrazides: A metal- And oxidant-free protocol for the synthesis of (: E)-vinyl sulfones in water

An efficient electrochemical transformation of a variety of alkenes and sulfonyl hydrazides into vinyl sulfones with a catalytic amount of tetrabutylammonium iodide in water is reported. The reaction proceeds smoothly to afford vinyl sulfones with good selectivities and yields at room temperature under air in an undivided cell. Cyclic voltammograms and control experiments have been performed to provide preliminary insight into the reaction mechanism. The key features of this reaction include using pure water as solvent, transition metal- and oxidant-free conditions, and being easily scaled up to gram-scale synthesis. This journal is
