Mn(iii)-mediated regioselective synthesis of (E)-vinyl sulfones from sodium sulfinates and nitro-olefins†
Abstract
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.
