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 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.
Described are coelenterazine analogs, methods for making the analogs, kits comprising the analogs, and methods of using the compounds for the detection of luminescence in luciferase-based assays.

Represented herein is a simple thiol identified as an effective precursor to photochemically form a carbocation. Thanks to the thiyl radical rapid transformation to disulfide, which serves not only to stabilize the generated thiyl radical but also to allow the second electron transfer to form a carbocation. The resulting carbocations, including primary benzylic, secondary, and tertiary carbocations
