carried out in the presence of cyclopentadiene. As a result, hetero‐Diels–Alder adducts of the thioaldehyde and the diene were formed. The treatment of a mixture of the thioformate and phenyl Grignard reagent with iodine gave 1,2‐bis(phenylsulfanyl)‐1,2‐diphenyl ethane as a product, which indicated the formation of arylsulfanyl benzylic Grignard reagents in the reaction mixture. When electrophiles were

The oxidative cleavage reaction of the C–Sbond using singlet oxygen is challenging because of its uncontrollable nature. We have developed a novel method for the singlet-oxygen-mediated selective C–Sbond cleavage reaction using silver(II)–ligand complexes. Visible-light-induced silver catalysis enables the controlled oxidative cleavage of benzyl thiols to afford carbonyl compounds, such as aldehydes

A novel Mitsunobu-based technique has been developed for the synthesis of a variety of symmetrical and unsymmetrical S,S-dialkyl dithiocarbonates from various corresponding primary, secondary and tertiary thiols using gaseous carbon dioxide, in good to excellent yields.

A novel method for the oxidative C–S bond cleavage of benzyl thiols was developed. In situ-activated silver species enabled the controlled bond cleavage of benzyl thiols to afford aldehydes and ketones in the absence of a photocatalyst. The desired carbonyl compounds were obtained undermild reaction conditionsvia two different reaction pathways.
