Murugesan, Kathiravan published the artcileVisible-Light-Promoted Metal-Free Synthesis of (Hetero)Aromatic Nitriles from C(sp³)-H Bonds, Name: 4,4′-Dimethyldiphenyl, the publication is Angewandte Chemie, International Edition (2021), 60(5), 2439-2445, database is CAplus and MEDLINE.

The metal-free activation of C(sp³)-H bonds to value-added products is of paramount importance in organic synthesis. We report the use of the com. available organic dye 2,4,6-triphenylpyrylium tetrafluoroborate (TPP) for the conversion of methylarenes to the corresponding aryl nitriles via a photocatalytic process. Applying this methodol., a variety of cyanobenzenes have been synthesized in good to excellent yield under metal- and cyanide-free conditions. We demonstrate the scope of the method with over 50 examples including late-stage functionalization of drug mols. (celecoxib) and complex structures such as L-menthol, amino acids, and cholesterol derivatives Furthermore, the presented synthetic protocol is applicable for gram-scale reactions. In addition to methylarenes, selected examples for the cyanation of aldehydes, alcs. and oximes are demonstrated as well. Detailed mechanistic investigations have been carried out using time-resolved luminescence quenching studies, control experiments, and NMR spectroscopy as well as kinetic studies, all supporting the proposed catalytic cycle.
