Fenton-Inspired C-H Functionalization: Peroxide-Directed C-H Thioetherification

Substoichiometric iron mediates the thioetherification of unactivated aliphatic C-H bonds directed by resident silylperoxides. Upon exposure to a catalytic amount of iron(II) triflate, TIPS-protected peroxides bearing primary, secondary, and tertiary C-H sites undergo chemoselective thioetherification of remote C-H bonds with diaryl disulfides. The reaction demonstrates a broad substrate scope and functional group tolerance without the use of any noble metal additives. Mechanistic experiments suggest that the reaction proceeds through 1,5-H atom abstraction by a hydroxyl radical generated with iron.

Decarboxylative Giese-Type Reaction of Carboxylic Acids Promoted by Visible Light: A Sustainable and Photoredox-Neutral Protocol

We describe herein a transition-metal-free method for the decarboxylative generation of radicals from carboxylic acids and their 1,4-addition to Michael acceptors. The Fukuzumi catalyst (9-mesitylene-10-methylacridinium perchlorate, [Acr-Mes]ClO4) enabled this transformation under visible-light irradiation at room temperature with CO2 as the only byproduct. The scope and limitations of this protocol were examined by using a range of Michael acceptors (15 examples) and carboxylic acids (18 examples). The use of 3-hydroxypivalic acid in this protocol allowed the straightforward formation of a diastereomerically pure δ-lactone. Moreover, when a homoallylic acid was used, a radical cascade reaction took place with the formation of three C–C bonds.

Synthesis of aryl perfluoroalkyl sulfides from aromatic disulfides

Thermolysis of xenon(II) bis(perfluoroalkanecarboxylates) in the presence of diaryl disulfides occurs through the S-S bond cleavage to form dihalo-, halonitro-, and halodinitrophenyl perfluoroalkyl sulfides. The latter type of compounds was obtained for the first time. The main side process is the perfluoroalkylation of the aromatic ring.
