Abstract
Photochemical and photocatalytic reactions of thioamides and thiophosphonyl diamides with iminoiodinanes have been developed. Blue-light promoted interaction of aromatic, aliphatic, and heterocyclic thioamides with iminoiodinane PhINTs furnished the corresponding N-sulfonyl amidines in 47–87% yields. A photocatalytic transformation of thiophosphonyl diamides in the presence of iminoiodinane PhINTs, catalyzed by Ru(bpy)3Cl2, was found to provide a route to phosphorus-containing N-sulfonyl amidines in 49–67% yields.
