The conjugate addition of amines to conjugated alkenes (commonly known as aza-Michael reaction) constitutes a key step for the synthesis of various complex natural products, antibiotics, α-amino alcohols and chiral auxiliaries. Ultrasound-induced addition of several amines to α, β-unsaturatedketones, esters and nitriles has been carried out very efficiently in water as well as under solvent-free conditions

1H-NMR, DFT and TDDFT methods. C–H bond activation was confirmed by sequential reactions and the data were supported by a one-pot synthesis product. Optimization of the intensity of visible light of the photocatalytic reactions. Finally, the sp2-H bond activation via the formation of the C–S and intramolecular C–C bonds in the presence of both the complexes were performed under visible light irradiation
