2012 m. Nr. 3 AgI nanoparticles as heterogeneous catalysts in one-pot alkylation reaction of chiral amines (L-valine methyl ester) in water-alcohol media
An efficient eco-friendly method for the alkylation reaction of various chiral amines is described by a simple one-pot reaction of aldehydes, amines and alkyl iodides in the presence of AgI nanoparticles in water-alcohol media. Silver iodide nanoparticles mediated the 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, decreased the reaction times in all cases and did not affect the reaction diastereoselectivity. The heterogeneous mediator was fully characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and FT-IR experimental techniques.
