Introduction: An instrumental strategy for α-iminonitrile derivatives preparation by
Fe3O4@cellulose-OSO3H (MCSA) as an eco-friendly nanocatalyst and oxidative agent in aerobic condition, is
Materials and Methods: Through this method, a one-pot three-component condensation reaction of various
aldehydes, primary amines and trimethylsilylcyanide (TMSCN) were applied to synthesize the desired
products. It was performed in absolute ethanol and under a mild condition by using the presented nanocatalyst.
High reaction yields were obtained through using the presented magnetic agent, as well. Moreover, the threecomponent
reactions were executed using accessible and economical precursors. The convenient separation
and recyclability of the used nanocatalyst were also precisely investigated.
Results and Discussion: In this research, we identified novel α-iminonitrile derivatives using 1H NMR, 13C
NMR, CHN, and FT-IR analyses, as well. In order to determine the well-known derivatives, we used FT-IR
method as well as comparing their melting points with those of reported.
Conclusion: In summary, an extremely efficient method was used for the environmentally-friendly synthesis
of α-iminonitrile derivatives that are important bioactive substances. The catalytic oxidative coupling reaction
afforded the products via a one-pot three-component condensation reaction of various aldehydes, primary
amines and TMSCN with great reaction yields, in ethanol under mild conditions.
