Cooperative Photometallobiocatalysis: Nonheme Fe Enzyme-Catalyzed Enantioconvergent Radical Decarboxylative Azidation, Thiocyanation, and Isocyanation of Redox-Active Esters. [PDF]
Through the directed evolution of an underexploited nonheme Fe extradiol dioxygenase, we developed a unified cooperative photobiocatalytic strategy to allow for three types of enantioconvergent radical transformations, including azidation, thiocyanation, and isocyanation.

Photoredox-Catalyzed Decarboxylative Bromination, Chlorination and Thiocyanation Using Inorganic Salts. [PDF]
Decarboxylative halogenations of alkyl carboxylic acids are highly valuable reactions for the synthesis of stucturally diverse alkyl halides. However, many reported protocols rely on stoichiometric strong oxidants or highly electrophilic halogenating ...

Cationic Selenuranes - Bench-Stable Sources of Se(III) Radicals. [PDF]
We present the synthesis of cationic selenurane salts via oligomerization of dibenzoselenophene‐based radical cations, allowing the formation of radicals without external activation. The salts can be prepared on a multigram scale and stored as solids for more than a month at ambient conditions.

Recent Synthetic Advances in C-H/N-H Functionalization of 1H-Pyrazoles: Diverse Strategies Across Variously Substituted Scaffolds. [PDF]
Systematic overview of pyrazole functionalization reactions from C‐5 to N−H. It covers different strategies, from traditional cross‐coupling of prefunctionalized pyrazoles to more efficient direct functionalizations. This review briefly and systematically overviews C–H and N–H functionalization reactions of pyrazoles, aimed at creating new CC and C ...

Photochemical Thiocyanation of Halobenzenes with Thiocyanate Anion [PDF]
Abstract Halobenzenes having such an electrondonating group as amino, hydroxyl or methoxyl group at their para position were thiocyanated with sodium thiocyanate under irradiation. Also, the ring isomer of o-thiocyanatoaniline, 2-aminobenzothiazole, was obtained by the photoreaction of o-chloroaniline with sodium thiocyanate.
