Recent Advances in Heterogenization of Photocatalysts on Polymer Supports and Applications in Organic Synthesis

open access: yesChemPhotoChem, Volume 9, Issue 5, May 2025.
This review focuses on recent developments in heterogenization of photocatalysts into polymers, highlighting methods like photocatalyst polymerization, post‐grafting, and 3D printing. Discussion about these different approaches of heterogeneous photocatalysis (advantages and drawbacks) is provided.

Pentathiepins are an understudied molecular prism of biological activities

open access: yesArchiv der Pharmazie, Volume 357, Issue 12, December 2024.
Pentathiepins are cyclic sulfur‐rich compounds that possess remarkable chemical stability, unique structural features, and an extraordinary variety of biological activities. Nonetheless, they have only drawn the attention of the scientific community on a few occasions, generally after the serendipitous discovery of some of their properties. This review

A Visible-Light-Promoted Aerobic Metal-Free C‑3 Thiocyanation of Indoles

open access: yes, 2016
A simple and efficient visible-light-promoted method for the C-3 thiocyanation of indoles has been developed. The transformation uses Rose Bengal as the photocatalyst and air as the terminal oxidant.

Oxidative trifluoromethylthiolation and thiocyanation of amines: a general approach to N–S bond formation†

open access: yes, 2016
International audienceHerein, we described a practical and efficient one-pot oxidative trifluoromethylthiolation of amines. A panel of primary and secondary amines was functionalized in good yields at room temperature.

Ferric (III) chloride-promoted electrophilic thiocyanation of aromatic and heteroaromatic compounds

open access: yes, 2005
Indoles, oxindoles and aromatic amino compounds undergo smooth thiocyanation with ammonium thiocyanate in the presence of anhydrous FeCl3 in dichloromethane under mild conditions to afford the corresponding 3-indolyl and 4-aryl thiocyanates, respectively,

Visible-Light-Promoted Aerobic α‑Thiocyanation of Carbonyl Compounds with Ammonium Thiocyanate

open access: yes
In the present study, we successfully developed an efficient thiocyanation of carbonyl compounds by using low-toxicity and inexpensive ammonium thiocyanate as the thiocyanate source under visible light in air (O2) at room temperature.
