The use of graphene derivatives as supports improves the properties of heterogeneous catalysts, with graphene oxide (GO) being the most frequently employed. To explore greener possibilities as well as to get some insights into the role of the different gr

A simple sulfonylation strategy involving I2 and thiosulfonates, as sulfonyl-group precursors, is reported for the synthesis of vinyl sulfones. Sulfonyl radicals are presumed to be generated from thiosulfonates, which subsequently react with st

An efficient Mn(iii)-mediated coupling reaction of sodium sulfinates with nitro-olefins has been developed, this reaction proceeds in mild and open-flask conditions to afford (E)-vinyl sulfones with high regioselectivities and in good to excellent yields. The control experiments revealed that this transformation could involve a radical process.

The first utilization of β-nitrostyrenes (readily available by the Henry reaction) for a highly stereoselective, convenient, and catalytic synthesis of (E)-vinyl sulfones at room temperature was investigated. The protocol involves efficient silver-catalyz

In this work, we have described an alternative alkenylation approach to illustrate the metal-like behaviour of iodine in cross-coupling reactions. Alkenylation could proceed through iodide catalysed radical initiation, radical addition and iodine promoted

Arenesulfonyl chlorides react with vinylarenes in the presence of dichlorotris(triphenylphosphine)ruthenium(II) catalyst and 1 molar equiv of a tertiary amine to form α,β-unsaturated sulfones 2.Only the E isomers of the sulfones are formed.In reactions of arenesulfonyl chlorides containing an electron-withdrawing Cl or NO2 substituent with α-methylstyrenes, 2-aryl-3-(arylsulfonyl)propenes (5) are also formed.Mechanisms for these reactions are proposed.
