A metal- and additive-free methodology for the highly selective, photocatalyzed C-H oxygenation of alkylarenes under air to the corresponding carbonyls is presented. The process is catalyzed by an imide-acridinium that forms an extremely strong photooxidant upon visible light irradiation, which is able to activate inert alkylarenes such as toluene. Hence, this is an easy to perform, sustainable and environmentally friendly oxidation that provides valuable carbonyls from abundant, readily available compounds.
A convenient [2+2] cycloaddition-cycloreversion reaction for the synthesis of 1,1-dicyanobuta-1,3-diene-scaffolded peptides as new imaging chromophores

We report on the chemoselective coupling between colorless peptide fragments functionalized with a mutually reactive electron-rich N α-(4-ethynylphenyl)-Nα-(methyl)-glycyl- and an electron-deficient [4-(2,2-dicyanovinyl)]benzoyl moie
