Technical Notes:
1. Visible light-promoted synthesis of spiroepoxy chromanone derivatives via a tandem oxidation/radical/cyclization/epoxidation process.
2. Visible light-promoted, asymmetric cross-dehydrogenative coupling of tertiary amines to ketones by synergistic multiple catalysis.
3. Photoredox catalysis enabled alkylation of alkenyl carboxylic acids with N-(acyloxy)phthalimide via dual decarboxylation
4. AlkyI esterification of vinylarenes enabled by visible -light-induced decarboxylation.
5. Photoredox- catalyzed C-H arylation of internal alkenes to tetrasubstituted alkenes .
6. Ru/Ni catalytic photoredox c (sp')-C(sp') cross-coupling of alkyl sulfinate salts and aryl halides.
