Synthesis of 1H-Isochromenes, 4H-Chromenes and Orthoaminocarbonitrile Tetrahydronaphthalenes by CaMgFe2O4 Base Nanocatalyst

Abstract

Designing protocols for the preparation of nanocatalyst in order to increase the yield of an organic reaction is a challenging task in modern chemistry. CaMgFe2O4 is a base nanocatalyst that prepared through sol-gel method. This nanocatalyst has used for the synthesis of 1H-isocromenes, 4Hchromenes and ortho-aminocarbonitrile tetrahydronaphthalenes through the multi-component reactions. The starting materials for all of the reactions are cyclohexanone, benzaldehyde and malononitrile and the reaction followed with Michael addition and cyclization. Therefore, the different multicomponent reactions from the same materials arranged by using CaMgFe2O4 base nanocatalyst. The catalyst identified with XRD, EDX, SEM, VSM and XPS techniques and the organic compounds recognized with melting point, FT-IR, 1HNMR and 13CNMR analyses.
