Photocatalyst‐, Base‐ and Additive‐Free, Visible‐Light Induced 1,3‐Thiosulfonylation of Allylboronic Esters and Allylketones with Thiosulfonates

This is the authors' abstract. We don't add key points for this paper.

A practical and highly efficient radical 1,3‐thiosulfonylation of allylboronic esters and allylketones with thiosulfonates via 1,2‐functional group migration is described, affording diverse 1,3‐thiosulfonylated products in good yields. Notably, this method can be performed under photocatalyst‐, base‐ and additive‐free conditions, which features operational simplicity, high atom‐economy, excellent functional group tolerance and versatile transformations of the products.
