Article Synopsis
- The study focuses on a metallaphotoredox catalyzed cross-coupling reaction between arylbromides (Ar-Br) and alkyl bis(catecholato)silicates (R-Si), using various analytical tools and modeling techniques.
- Researchers identified four key control parameters: concentrations of the iridium photocatalyst, nickel precatalyst, silicate, and light intensity, which affect the reaction's efficiency.
- Two distinct reaction pathways were discovered: one leads to the desired product Ar-R without side products, while the other results in the degradation of R-Si to R-H alongside the formation of Ar-R.
While the generation of aryl radicals by photoredox catalysis under reductive conditions is well documented, it has remained challenging under an oxidative pathway. Because of the easy photo-oxidation of alkyl bis-catecholato silicates, a general study of phenyl silicates bearing substituted catecholate ligands has been achieved. The newly synthesized phenyl silicates have been fully characterized, and their reactivity has been explored.
