The aim of this research is to establish how metal-organic frameworks (MOFs) composed of more than one metal in equivalent crystallographic sites (solid solution MOFs) exhibit catalytic activity, which is tunable by virtue of the metal ions ratio. New MOF

High pressure (600 MPa) reaction conditions, in the absence of a catalyst, have proved to be a powerful way to stimulate the three component Strecker reaction synthesis of α-aminonitriles in high yields. Examples of two types of double Strecker reactions were also described.

Abstract: A new multifunctional bimetallic nanocatalyst was prepared by immobilization of Cu/Ni-doped sulfated zirconium oxide on magnetic cadmium ferrite (CdFe2O4@SiO2@ZrO2/SO42?/Cu/Ni) and used as an efficient recyclable catalyst for one-pot as well as stepwise preparation of α-aminonitriles under mild conditions. The magnetic nanocatalyst was characterized by FTIR, TGA, VSM, XRD, EDX, FE-SEM, and TEM analyses. Also, the surface acidity of the catalyst was measured by pyridine adsorption assay. The catalyst possesses various active sites which could catalyst a variety of aromatic and aliphatic aldehydes to the corresponding α-amionitriles under moderate to high yields in the presence of aniline. Furthermore, transformation of ketones to the desired α-amionitriles and some bis-aminonitriles was also performed by this method. The catalyst could be readily recovered from the reaction mixture and reused for several times without significant loss of activity. Graphic abstract: A general and efficient method has been developed for transformation of a variety of aliphatic, aromatic aldehydes and ketones to the corresponding α-aminonitriles using a multifunctional recyclable CdFe2O4@SiO2@ZrO2/SO42?/Cu/Ni nanocatalyst.[Figure not available: see fulltext.]

Synthesis of α-Aminonitriles and 5-Substituted 1H-Tetrazoles Using an Efficient Nanocatalyst of Fe3O4@SiO2–APTES-supported Trifluoroacetic Acid

Fe3O4@SiO2–APTES-supported trifluoroacetic acid nanocatalyst was used for the one-pot synthesis of α-aminonitriles via a three-component reaction of aldehydes (or ketones), amines, and sodium cyanide. This method produced a high yield of 75–96% using only a small amount of the catalyst (0.05?g) in EtOH at room temperature. The catalyst was also employed for the synthesis of 5-substituted 1H-tetrazoles from nitriles and sodium azide in EtOH at 80°C. The tetrazoles were produced with good-to-excellent yields in a short reaction time of 4?h. Both synthetic methods were carried out in the absence of an organic volatile solvent. Because the supported trifluoroacetic acid generated a solid acid on the surface, thus the acid corrosiveness was not a serious challenge. This heterogeneous nanocatalyst was magnetically recovered and reused several times without significant loss of catalytic activity.

Abstract: Gallic acid-coated magnetic nanoparticles were efficiently prepared, characterized by Fourier transform infrared spectroscopy, X-ray diffraction, vibrating sample magnetometry, scanning electron microscopy, and transmission electron microscopy, and employed as an environmentally friendly and recyclable catalyst for one-pot synthesis of three-component reaction via Strecker reaction, incorporating aldehydes/ketones, amines, and trimethylsilyl cyanides under solvent-free conditions. Operational simplicity, product purity, natural resources and reusability of the catalyst are considered as evident features of this protocol which will hopefully develop into an inexpensive, efficient, and clean strategy for the synthesis of α-aminonitriles.
