Abstract

In the first stage of this project, a new spherical nanostructure in the form of magnesium bismuth was prepared by co-precipitation method using N-cetyl-N,N,N-trimethylammonium bromide as an ionic surfactant. The nanostructures were detected by techniques such as SEM, EDX, XRD and FT-IR. In the next step, the efficiency of this catalyst is used in the three-part reaction of indoles, thiols and benzaldehydes under solvent-free conditions at a temperature of 120 ° C to synthesize derivatives of 3-[(alkyl/arylthio)(aryl)methyl]-1H-indoles. Features such as recyclability and reusability at least in three cycles without reducing catalyst power, environmental friendliness, cheapness, cost-effectiveness and high stability are the advantages of this nanocatalyst. High efficiency of products and relatively short times, easy and simple working method and absence of hydrocarbon and toxic solvents are very important advantages of the proposed method. In the final section, a comparison is made between this catalyst and the cases reported in the articles for the synthesis of this type of anomalous compounds containing nitrogen and sulfur.
