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.

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
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.

Copper-catalyzed aerobic oxidative C-S bond coupling reaction between thiophenols and aryl-substituted alkenes for (E)-vinyl sulfones synthesis is reported here. With air utilized as a green oxidant, this transformation not only produces various vinyl sulfones in moderate to good yields but also possesses a simple and ecofriendly system. To clarify the mechanism, kinetic experiments has been investigated.
