Oxime chemicals are the building blocks of many anticancer drugs and widely used in industry and laboratory. A simple but robust hierarchically porous zeolite (HTS‐1) catalyst was prepared by hydrothermal method and used for the preparation of vanillin oxime from vanillin in NH3·H2O/DIO (v/v 1/10) system. The results of the catalyst characterization showed that the larger pore size and more framework Ti were conducive to promote the transformation of the substrates. The conversion of vanillin and the yield of vanillin oxime were both higher than 99% under optimized reaction conditions. It was found that the reaction proceeded by oxidation of NH3 to hydroxylamine (NH2OH), and oximation of hydroxylamine with vanillin to obtain vanillin oxime, where the rate‐controlling step was the hydroxylamine formation, and the apparent activation energy was 26.22 kJ/mol. The corresponding oximation products could also be obtained by extending this method to other compounds derived from lignin. Furthermore, the catalytic system was used directly to the conversion of birch biomass to obtain oxime products such as vanillin oxime, syringaldehyde oxime, and furfural oxime et al.. This work might give insights into the sustainable production of N‐containing high‐value products from lignocellulose.

“…On the other hand, magnetic nanoparticles (MNPs) have particularly drawn attention as their magnetic properties can greatly facilitate the application and separation of compounds. [ 39–42 ] Magnetic isolation is eco‐friendly, quick, and more effective than centrifugation and filtration. [ 43–46 ] Among the various MNPs, Fe 3 O 4 seems to be the most interesting magnetic substance for the catalyst support; however, Fe 3 O 4 is quite chemically unstable.…”

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.

In this work, novel magnetic nanoparticles CoFe2O4/MCC (microcrystalline cellulose) @L‐aspargine‐Co have been synthesized via simple procedure and have been fully characterized using several techniques such as scanning electron microscopy (FE‐SEM), transmission electron microscopy (TEM), energy‐dispersive X‐ray spectroscopy (EDX), X‐ray atomic mapping, powder X‐ray diffraction (XRD), Fourier transform spectroscopy infrared (FT‐IR) and coupled plasma optical emission spectrometry (ICP‐OES). The catalytic efficiency of this nanocatalyst has been examined in the eco‐friendly reduction of different substituted nitro compounds to corresponding amines with sodium borohydride (NaBH4). The reactions were conducted in water at room temperature with high turnover numbers (TON) and turnover frequencies (TOF). The nontoxic nature, green reaction conditions, short reaction times, simple work‐up method and elimination of by‐products are some advantages of this approach. This organometallic catalyst was successfully recycled for eight times without losing the catalytic efficiency.
