Control of the synthesis and morphology of nano dendritic CuAl2O4 as a nanocatalyst for photoredox-catalyzed dicarbofunctionalization of styrenes with amines and CO2.

Various morphologies of a nano CuAl2O4 fiber microsphere were produced through diverse synthesis situations. The findings showed that the morphology, anatomy, and quantity of the fibers in the CuAl2O4 product are vigorously correlated with the various mechanical pressures, calcination, and hydrothermal processing time. Subsequent research has also shown that the best type of sample offers a variety of catalytic functions for carbocarboxylation of styrenes deploying CO2 and amines by reducing the efficiency of dandelion-like CuAl2O4 fiber anatomy. The reaction is catalyzed by the photoredox catalyst and is adaptable with various amines and styrenes. This approach provides extremely functionalized γ-amino acids in satisfactory efficiencies with extreme regioselectivity. The reported synthesis is the first example of visible light induced synthesis of a γ-amino acid from CO2 and includes several advantages like environmentally benign reaction conditions, a minimum amount of catalyst due to fiber structure, cost effectiveness, operational simplicity, short reaction times, excellent yields, and high atom economy, making it a genuinely green protocol.
