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

Abstract. A practical and highly efficient radical 1,3‐thiosulfonylation of allylboron 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.
