Thioxanthone is a powerful photocatalyst. In this review, its photophysical properties and its applications in photopolymerisation and in organic synthesis are highlighted.

This review highlights the use of Cyrene as an alternative green solvent in organic synthesis.

Green oxidation reactions performed by organocatalytic activation of hydrogen peroxide.

Photochemical aerobic synthesis of sulfoxides from sulfides, utilizing air as the oxidant, 2-Me-THF as the green solvent and LED 370 nm. 427 nm, CFL or sunlight as the irradiation source. Application in the synthesis of sulforaphane and modafinil.

Cyrene is employed as the reaction medium in the Mizoroki–Heck cross-coupling between aryl iodides with acrylates, acrylamides or styrene. Its application in the synthesis of piperlotine A is demonstrated.

Over the past decade with the relaunch of photochemistry, photochemical cross‐coupling reactions became an excellent tool for the formation of C−C bond under mild reaction conditions. C(sp³)−H functionalization of inert substrates, combined with modern transition metal catalysis, provides a powerful tool in organic synthesis. A variety of elegant strategies to initiate a HAT event have been developed, generating alkyl radicals that can be easily intersected with a metal. This review conceptualizes the recent developments in this area, linking them with the seminal contributions that pioneered this research field.
