readily available aldehydes, primary amines and 4-alkyl-1,4-dihydropyridines (alkyl-DHPs) for the synthesis of secondary amines at room temperature under visible light irradiation has been accomplished. This transformation occurs smoothly under mild conditions to enable facile access to various secondary amines with high efficiency, wide substrate scope and good functional group tolerance, and can be

An efficient ecofriendly method for the alkylation reaction of various imines is described by a simple one-pot reaction of aldehydes, amines and alkyl iodides in the presence of AgI nanoparticles in aqueous media. Silver iodide nanoparticles mediated an enhanced rate and facility of reaction and showed high influence in the green synthesis of some amine derivatives. Moreover, this nanoparticle increased the yields of products and decreased the reaction times in all cases. The heterogeneous mediator was fully characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and FT-IR experimental techniques.
