A novel catalyst based on layered double hydroxides coated with copper nitrate [LDH@(3-chloropropyl)trimethoxysilane@N1,N4-bis(4,6-diamino-1,3,5-triazin-2-yl)benzene-1,4-disulfonamide@Cu] was successfully synthesized. The structure of the new synthesized catalyst was investigated and confirmed using different analytical techniques, such as Fourier-transform infrared spectroscopy (FTIR), energy-scattered X-ray spectroscopy (EDX) mapping, X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), and heat gravity/heat derivatization (TGA/DSC). The skilled catalyst proved its efficiency for one-pot three-component synthesis of pyrano [2,3-d]pyrimidine and new dihydropyrazolo[4′,3′:5,6]pyrano[2,3-d]pyrimidine-dione derivatives. Using this efficient catalyst, products were synthesized with a high yield, in a short time, and under soft and solvent-free conditions. The catalyst can be recovered and reused four times without a significant loss of efficiency.

Multicomponent reactions are reactions in which three or more are agreeable of raw interests, composed in a one-step chemical process and the product is formed they give. Since multivariate reactions are monovalent reactions and Single-step conversions to ideal synthesis are very close. In this research, one pot three components reaction was carried out between 1, 3-dimethylbarbituric acid, malononitrile and different aldehydes in the attendance of Cu/Co/Ni/MWCNTs as a recyclable catalyst. This catalyst indicated high catalytic actuality with good pro ciency and reusable under mild reservation. This reaction is performed ne at ambient temperature. This method proposed numerous materials such as being environmentally amicable for short reaction times and creating high yield products. The catalysts were collected and speci ed with diversity spectroscopic, such as techniques, such as FT-IR, X-ray fracture, and scanning electron microscopy. After nalization of the reaction, the vintage was obsolete, puri ed and identi ed by the melting points, infrared spectroscopy (FT-IR) and the magnetic resonance of the hydrogen nucleus ( 1 H NMR) techniques.

In the current research, much attention is paid to heterogenized nanostructure. Herein, we report the green synthesis magnetic nanoparticles (MNPs) of cobalt ferrite by the immobilization of erbium (Er) coated with folic acid (FA) which show effective catalytic properties and recyclability. Full characterizations with field emission scanning electron microscopy (FE‐SEM), transmission electron microscopy (TEM), energy‐dispersive X‐ray spectroscopy (EDX), X‐ray atomic mapping, thermal gravimetric analysis (TGA), X‐ray diffraction (XRD), vibrating sample magnetometer (VSM), inductively coupled plasma‐optical emission spectrometry (ICP‐OES), and Fourier‐transform infrared (FT‐IR) spectroscopy techniques were undertaken to uncover structural properties of the prepared magnetic catalyst. The obtained nanohybrid complexes as efficient, recyclable, and green heterogeneous systems pave the way for producing pyrano[2,3‐d]pyrimidinone and dihydropyrano[3,2‐c]chromenes derivatives by the one‐pot three‐component condensation reaction of various aldehydes, malononitrile, and hydroxycoumarin or barbituric acid in green condition. This easily prepared organometalic catalyst presents many superiorities such as operational simplicity, high yield, short reaction time, utilization of commercially available or easily accessible starting materials, eco‐friendly properties, and excellent purity. Most importantly, erbium‐FA‐coated CoFe2O4 can be easily separated and recycled from the reaction system using an external magnetic field. The magnetically recoverable biocatalyst can be recycled and reused six times while maintaining high activities. The activity of the magnetic catalyst can be maintained at more than 80% of that of the previous cycle. This research solves the recovery problem encountered in industrial applications of biocatalysts and presents a clean and green method for preparing pyrimidinones and chromenes.
